Zivan NG3 Current Limit Alternation.
Please observe safety precautions
Steps:-
Need DC Clamp meter , DC volt meter & load / flat battery to draw max current from the charger
Disconnect the charger from AC supply & batteries.
Open Charger Cover by removing 4 screws. Be careful not to snap the "Selector Detail" switch when
removing the cover.
Locate the Blue POT marked "I " - Next to IC "U5" on the vertical control PCB.
Connect AC supply / / Load bank to the charger and turn ON the charger.
Ensure the charger is in C/L by monitoring the volts / amps from the meter.
Slowly turn the POT "I" while monitoring the output current via the DC clamp meter.
Depending on the direction of turn Current will either increase / or decrease.
Set the Current Limit to 15Amps .
Verify this setting by putting enough load to force the charger into current limit. (If you are using a flat battery
as the load, the current may have actually dropped due to recharging of the battery)
