INTRODUCTION
This unit is a two stage, constant
voltage battery charger with current
limiting, current fold back, and
automatic temperature compensation
of the output voltage. It is protected
against shorting the output terminals
and reversing the output terminals on a
battery. It is equipped with an IEC-
60320 type power input module with
fuse holder and a spare fuse. A 6' long
detachable power cord with NEMA 5-
15P plug is provided for use in North
America. Other power cords can be
ordered with plugs designed to mate
with receptacles in other countries.
There is an input voltage selection
switch located above the input module to select between 115 and 230 VAC. The standard
output cable is 3' long with insulated boots and spring clips. There is one indicator light
on the front panel. It lights green to indicate when power is applied and, when a battery is
attached, that the charger is in float mode. It lights yellow when the unit is charging the
battery. It lights red to indicate a fault condition (shorted or reversed output connector).
The unit has a full metal enclosure to ensure field reliability.
This unit is designed to automatically switch into a single stage, float charge mode when
the battery is charged. A single stage, parallel charger version is available for keeping a
battery fully charged when used with a permanent or intermittent parallel load. The use of
an optional low voltage cut out is recommended when using parallel loads. This unit is
not designed to operate as a standalone power supply.
OPERATING INSTRUCTIONS
Before using this battery charger, make sure it is compatible with your battery. Refer to
the ratings on the battery charger, the specifications in this manual, and your battery
documentation. Charge only sealed of valve regulated, lead-acid, non-automotive,
maintenance free rechargeable batteries. Attempting to charge other types of batteries
may result in battery damage.
Determine the battery polarity. Most batteries identify the positive terminal with a “+”
sign or the color red and identify the negative terminal with a “
−
” sign or the color black.
Connect the red insulated output clip to the positive battery terminal and connect the
black insulated output clip to the negative battery terminal. If the charger is provided with
a polarized connector, make sure your battery connector is wired to match the output
connector.
