6 VOLTAGE/CURRENT REGULATION
6.1 VOLTAGE REGULATION
If adjust voltage on-site, battery need to be disconnected with battery charger, and then adjust the
voltage potentiometer (VOLT) to the appropriate value while measuring the charger output voltage.
6.2 CURRENT REGULATION
After connecting output port to the storage battery, measuring charging current under 25.0V charging
voltage, and then adjust the current potentiometer (AMP) to the appropriate value. Current also can be
estimated according to the scale of the current potentiometer.
7 OPERATION
7.1 MASK DESCRIPTION
─
Connect terminals L and N to alternating voltage (100~240)V, using BVR 1mm
2
multi-strand copper line.
─
Connect B+ and B- to battery positive and negative using multi-strand BVR1.5mm
2
copper
wires.
─
POWER: power supply indicator, illuminated when the charger is operating normally.
─
CHARGING: charging indicator, illuminated when charging current exceeds 0.5A while
extinguished when charging current has fallen below 0.5A.
─
VOLT: charging voltage regulator-potentiometer
─
AMP: charging current regulator-potentiometer
─
FUSE: output fuse; rated current: 10A. If connected in the wrong way, the fuse will be
burnt out and then voltage free. In this case connect cables correctly, replace the fuse and
the system will continue to operate normally.
NOTE:
1) Because there is diode and current-limiting circuit inner the charger, it can be used together with charging
generator, and there is no need to disconnect the charger when cranking
2) During genset is running, high current will cause voltage drop in charging line, so recommend separately
connecting to battery terminal to avoid disturbance on sampling precision.
