Charger models of type indicated in the heading above
are listed in the table below with either a "FloatCharge" or "3StepCharge"
algorithm by model selection (see Notes 1, 2, and 3 under the table), with
universal input, and with IEC 320 input connector
, and with 2conductor power output cable with a connector on its end to
connect to a customerfurnished mating connector leading to battery system
(or with other terminations such as alligator clips, etc.; note that an
inline fuse is needed in the (+) output lead wire somewhere between
the charger and the battery system). An optional 2conductor
cable can be provided with a connector on its end to connect to a customerfurnished
mating connector leading to a thermistor to sense the battery system temperature.
Knowing your battery's (1) "number
of cells and AH rating", (2) whether you want 3stage charge or float charge,
and (3) whether you want 2.45 v/cell or 2.4v/cell for "bulk and absorption
phases" of 3stage charge, then look in the table below to determine if
this group of chargers have charge current ratings suited to the recharge
time required for your application.

Notes:
1) Float charge models (also called singlemode)
are for use when batteries are being used as standby in event of a power
failure or when the charger is always connected to the battery during discharge.
Our standard for float charge voltage set point is 2.3v/cell. Other
set points can be offered if the 2.3v/cell is not suited to a customer's
requirement.
2) A 3step charge algorithm consists of (1) bulk
or fast charge phase, (2) absorption or taper charge phase, and (3) float
or maintenance charge phase. These 3step charge models are for use
when batteries are repeatedly being discharged and recharged; and these
charger models will fully recharge batteries more quickly without danger
of overcharge. The "bulk and absorption phases" have the same voltage
set point for 3step charger models. We offer two different standard
voltage set points for the "bulk and absorption phases", namely 2.4v/cell
and 2.45v/cell as noted by separate line items in the above table for similar
battery systems (ask the battery manufacturer which one is to be used).
The standard voltage set point for the float phase in the 3step models
is 2.3v/cell.
3) The 3step chargers are not typically connected
to the battery during discharge to a connected load. Contact
technical support for information on modifications that can be made so
that 3step chargers can be safely used to "fast charge" the battery during
discharge to a connected load.

Charger models of openframe type indicated in the heading
above are listed in the table below with either a "FloatCharge" or "3StepCharge"
algorithm by model selection (see Notes 1, 2, and 3 under the table), with
universal input, and with three (3) 0.11" Fastons
for input wire connections to the charger unit, and with
two (2) 0.11" Fastons for output wire connections to the battery system
(note that an inline fuse needs to be customerinstalled in the
(+) output lead wire somewhere between the charger and the battery system).
An optional connection to sense battery system temperature can be
made using two (2) 0.11" Fastons on the charger unit for connecting two
(2) wires to connect to a diode (sensor) located next to the batteries
to sense the battery system temperature.
Size: 6.20" long x 2.96"
wide x 1.94" high. Weight: 1.0 lbs. (approx.)
Knowing your battery's (1) "number
of cells and AH rating", (2) whether you want 3stage charge or float charge,
and (3) whether you want 2.45 v/cell or 2.4v/cell for "bulk and absorption
phases" of 3stage charge, then look in the table below to determine if
this group of chargers have charge current ratings suited to the recharge
time required for your application.

Notes:
1) Float charge models (also called singlemode)
are for use when batteries are being used as standby in event of a power
failure or when the charger is always connected to the battery during discharge.
Our standard for float charge voltage set point is 2.3v/cell. Other
set points can be offered if the 2.3v/cell is not suited to a customer's
requirement.
2) A 3step charge algorithm consists of (1) bulk
or fast charge phase, (2) absorption or taper charge phase, and (3) float
or maintenance charge phase. These 3step charge models are for use
when batteries are repeatedly being discharged and recharged; and these
charger models will fully recharge batteries more quickly without danger
of overcharge. The "bulk and absorption phases" have the same voltage
set point for 3step charger models. We offer two different standard
voltage set points for the "bulk and absorption phases", namely 2.4v/cell
and 2.45v/cell as noted by separate line items in the above table for similar
battery systems (ask the battery manufacturer which one is to be used).
The standard voltage set point for the float phase in the 3step models
is 2.3v/cell.
3) The 3step chargers are not typically connected
to the battery during discharge to a connected load. Contact
technical support for information on modifications that can be made so
that 3step chargers can be safely used to "fast charge" the battery during
discharge to a connected load.

Charger models of type indicated in the heading above
are listed in the table below with either a "FloatCharge" or "3StepCharge"
algorithm by model selection (see Notes 1, 2, and 3 under the table), with
universal input, and with IEC 320 input connector
, and with 2conductor power output cable with a connector on its end to
connect to a customerfurnished mating connector leading to battery system
(or with other terminations such as alligator clips, etc.; note that an
inline fuse is needed in the (+) output lead wire somewhere between
the charger and the battery system). An optional 2conductor
cable can be provided with a connector on its end to connect to a customerfurnished
mating connector leading to a thermistor to sense the battery system temperature.
Knowing your battery's (1) "number
of cells and AH rating", (2) whether you want 3stage charge or float charge,
and (3) whether you want 2.45 v/cell or 2.4v/cell for "bulk and absorption
phases" of 3stage charge, then look in the table below to determine if
this group of chargers have charge current ratings suited to the recharge
time required for your application.

Notes:
1) Float charge models (also called singlemode)
are for use when batteries are being used as standby in event of a power
failure or when the charger is always connected to the battery during discharge.
Our standard for float charge voltage set point is 2.3v/cell. Other
set points can be offered if the 2.3v/cell is not suited to a customer's
requirement.
2) A 3step charge algorithm consists of (1) bulk
or fast charge phase, (2) absorption or taper charge phase, and (3) float
or maintenance charge phase. These 3step charge models are for use

Notes:
1) Float charge models (also called singlemode)
are for use when batteries are being used as standby in event of a power
failure or when the charger is always connected to the battery during discharge.
Our standard for float charge voltage set point is 2.3v/cell. Other
set points can be offered if the 2.3v/cell is not suited to a customer's
requirement.
2) A 3step charge algorithm consists of (1) bulk
or fast charge phase, (2) absorption or taper charge phase, and (3) float
or maintenance charge phase. These 3step charge models are for use
when batteries are repeatedly being discharged and recharged; and these
charger models will fully recharge batteries more quickly without danger
of overcharge. The "bulk and absorption phases" have the same voltage
set point for 3step charger models. We offer two different standard
voltage set points for the "bulk and absorption phases", namely 2.4v/cell
and 2.45v/cell as noted by separate line items in the above table for similar
battery systems (ask the battery manufacturer which one is to be used).
The standard voltage set point for the float phase in the 3step models
is 2.3v/cell.
3) The 3step chargers are not typically connected
to the battery during discharge to a connected load. Contact
technical support for information on modifications that can be made so
that 3step chargers can be safely used to "fast charge" the battery during
discharge to a connected load.

Charger models of type indicated in the heading above
are listed in the table below with either a "FloatCharge" or "3StepCharge"
algorithm by model selection (see Notes 1, 2, and 3 under the table), with
universal input, and with IEC 320 input connector,
with Anderson Power Pole output connector on charger unit for connection
of the customer furnished output power cable to connect to the battery
system (note that an inline fuse is needed in the "plus" output
lead wire somewhere between the charger and the battery system), and
with a separate DIN connector on charger unit for connection of a customerfurnished
2wire cable to connect to a thermistor to sense the battery system temperature.
Knowing your battery's (1) "number
of cells and AH rating", (2) whether you want 3stage charge or float charge,
and (3) whether you want 2.45 v/cell or 2.4v/cell for "bulk and absorption
phases" of 3stage charge, then look in the table below to determine if
this group of chargers have charge current ratings suited to the recharge
time required for your application.

Notes:
1) Float charge models (also called singlemode)
are for use when batteries are being used as standby in event of a power
failure or when the charger is always connected to the battery during discharge.
Our standard for float charge voltage set point is 2.3v/cell. Other
set points can be offered if the 2.3v/cell is not suited to a customer's
requirement.
2) A 3step charge algorithm consists of (1) bulk
or fast charge phase, (2) absorption or taper charge phase, and (3) float
or maintenance charge phase. These 3step charge models are for use
when batteries are repeatedly being discharged and recharged; and these
charger models will fully recharge batteries more quickly without danger
of overcharge. The "bulk and absorption phases" have the same voltage
set point for 3step charger models. We offer two different standard
voltage set points for the "bulk and absorption phases", namely 2.4v/cell
and 2.45v/cell as noted by separate line items in the above table for similar
battery systems (ask the battery manufacturer which one is to be used).
The standard voltage set point for the float phase in the 3step models
is 2.3v/cell.
3) The 3step chargers are not typically connected
to the battery during discharge to a connected load. Contact
technical support for information on modifications that can be made so
that 3step chargers can be safely used to "fast charge" the battery during
discharge to a connected load.

Charger models of type indicated in the heading
above are listed in the table below with either a "FloatCharge" or "3StepCharge"
algorithm by model selection (see Notes 1, 2, and 3 under the table), with
universal input, and with IEC 320 input connector,
with Anderson Power Pole output connector on charger unit for connection
of the customer furnished output power cable to connect to the battery
system (note that an inline fuse is needed in the "plus" output
lead wire somewhere between the charger and the battery system), and
with a separate DIN connector on charger unit for connection of a customerfurnished
2wire cable to connect to a thermistor to sense the battery system temperature.
Knowing your battery's (1) "number
of cells and AH rating", (2) whether you want 3stage charge or float charge,
and (3) whether you want 2.45 v/cell or 2.4v/cell for "bulk and absorption
phases" of 3stage charge, then look in the table below to determine if
this group of chargers have charge current ratings suited to the recharge
time required for your application.
