All the EMC tests are been executed by mounting the unit on a 720mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwellcom) 5.The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft). 6.Please refer to respective specs of PSU models for the maximum number RKP-CMU1 can control and monitor. * Product Liability Disclaimer: For detailed information, please refer to https://www.meanwell.com/serviceDisclaimeraspx | ||
Function Manual
- 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.
- 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. - 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. - 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.
