Function Module (CPS300-N18A1H)
Functions
The function module integrates power unit (power rectification and distribution) and a network equipment. It converts AC power or DC solar power into stable 12 V DC, 24 V AC, and 53 V DC power, generates fault alarms, and reports monitoring data to the upstream network management system (NMS) in real time.
