Ac Charger - Ultimate Power UP12/2000SD-CG User Manual

Caution:
After the inverter is switched on, it takes a finite time for it to self-diagnoses and get ready to deliver
full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter.
Avoid switching on the inverter with the load already switched on. This may prematurely trigger the
overload protection. When a load is switched on, it may require initial higher power surge to start.
Hence, if multiple loads are being powered, they should be switched on one by one so that the
inverter is not overloaded by the higher starting surge if all the loads are switched on at once.

3.2 AC Charger

SD Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The
PFC feature is used to control the amount of power used to charge the batteries in order to obtain a
power factor as close as possible to 1. Unlike other inverters whose max charging current decreases
according to the input AC voltage, SD Series charger is able to output max current as long as input
AC voltage is in the range of 95-127VAC, and AC freq is in the range of 58-64Hz. The SD Series
inverter possesses a strong charging current of 110Amp (for 4KW 12Vdc model), and the max
charge current can be adjusted from 0%-100% via a liner switch to the right of the battery type
selector. This will be helpful if you are using our powerful charger on a small capacity battery bank.
Choosing "0" in the battery type selector will disable charging function.
