Function Manual

1. Communication interface
   RKP-CMU1 can control and monitor parameters of power units via PMBus communication, and PC can manage the whole system by using USB, RS232, or Ethernet to connect to RKP-CMU1.
   PMBus: RKP-CMU1 supports PMBus Rev. 1.1 with maximum 100KHz bus speed, allowing information reading, status monitoring and output trimming. For details, please refer to the Installation Manual.

2. Monitoring and control
   RKP-CMU1 can monitor parameters of power units such as output voltage, output current, internal temperature, status, serial number, and firmware version. It also can turn power units on/off together or separately by using “ON/OFF’ pin in CN500 or PMBus “CONTROL” pin in JK1 or PMBus ‘OPERATION” command, shows below. By using PMBus, output voltage and over load protection of power units are adjustable. Please refer to the Installation Manual.

3. Real time clock, Data Log and Event Log
   RKP-CMU1 has a build-in real time clock data to display actual date/time and for log time stamp. The data logger is designed to store operating data when the systems works. It has 1000 recodes and the interval of log is programmable from 1 to 60 minutes. The event log store system condition when alarm occur and remove. There are 600 records in event log.

4. Programmable relay
   There are 4 relays and each relay has normal open, normal close and common contact in terminal block. Their active conditions are programmable for flexible application, like charger and generator control.
