I. General
This m
odel of power supply is systemic one which features wide input voltage range, output voltage
54.5V, max output current 5A for single rectified module, and floating charge for battery. System has two
rectified modules which are integrated, and then output. Output voltage refers to voltage after integration.
There is a monitoring module that communicates with supervisory control computer by RS232 to monitor
power supply and battery.
