Features
5
Switch-Mode Design: High-
efficiency operation with smooth,
ripple-free DC output.
6
10-LED Display: Displays state of
charge and charge error conditions.
7
Charge Protection: Protects from
improper connection, overload and
excessive temperatures.
8
Programmed safety features include
charge time monitoring and over
temperature protection.
9
Charge Algorithm: I-E-I - constant
current/constant voltage/constant
current charge profile.
10
Pre-Test: Performs several
diagnostic tests before charging
begins.
11
7-9
Multi-Charge Steps: Ensures a
consistent and repeatable charge.
Step 1: Pre-test: Tests several
conditions before charging begins.
If a problem is detected, charging is
terminated.
Step 2: Constant Current Step:
Battery is charged with full rated
output current, restoring up to 80%
of charge.
Step 3: Constant Voltage Step:
Regulated voltage "equalizes"
individual battery cells, resulting in
full charge delivered to the battery.
Step 4: Topping Off Step: Battery
pack is brought slowly to full charge
without excess gassing.
Step 5: Storage: Every 14th day
and if voltage becomes less than
48V, charger restarts cycle to
refresh batteries in storage.
Automatic Battery Equalization
(Boosting): Automatically boosts
battery pack when individual cell-
voltages are not balanced and
restores pack capacity.
