2-3 Introduction on function of main module

2-3-1 Rectifier / battery charger

(1) Rectifier / battery charger module is using SCR components for transforming AC to DC voltage

and to recharge the batteries.

(2) In Rectifier / battery charger module, double control method to CPLD and DSP are combined to

keep rectifier and battery charger more steady and reliable.

(3) Has complete system for protection from over voltage.
(4) Detection on phase sequence error or single phasing.
(5) Equipped with function to soft start the DC voltage during power up or return of utility power.
(6) Designed with 3 phases and 6 pulses. Optional six phase 12 phase pulse is available.
(7) It supports float charge and equalization charge for maintenance free battery. Floating charge

voltage is DC 420V, equalization charge voltage is DC 430V, floating charge voltage is 410V.

starting up and recovery. Meanwhile the UPS keeps communication with other device as it were.

For recovering from EPO, push the EPO switch while pressing the “OFF” button on the LCD panel
and a screen for confirming setting appears. Press “ENTER” button. The DSP system will respond in a
few seconds and “Setting complete” appears to indicate setting successfully. At the moment check the
voltage reading on the screen if the voltage of battery reaches to 410VDC. If it reads 410VDC, switch
off S4 breaker at once. The system will detect the battery for 30 seconds and after the procedure, DC
will recover and the UPS will transfer form Bypass mode to Inverter mode. At this point, the UPS is
powered by the INVERTER.

6 Maintenance

(1) Keep the operating environment clean and clean the inside of the UPS at least once a year.
(2) Discharge and charge the battery at least once every three months to improve the life of the

battery.
