Rack power monitoring units

8 February 2012 Power Electronics / Power Management

Mean Well launched new peripheral control and monitoring units to complement its RCP-2000 rack power unit and provide a complete rack power solution.

The new RKP-CMU1 is a single control and monitoring unit with 1U low-profile design, while the RKP-1Ux-CMU1 is a 19-inch 1U rack mounting system with installed capacity for two RCP-2000 units and one


RKP-CMU1. Both models are powered by an external adapter which is available as an optional extra.

Up to 32 RCP-2000s can be monitored by one RKP-CMU1 and the information of output voltage, output current, internal temperature, operating status for each unit, series number and firmware version of each RCP-2000 can be shown on the LCD front panel. Using the buttons on the front panel of the RKP-CMU1, each RCP-2000 can be turned on or off directly and the output voltage as well as current limit point of each unit can be trimmed. In addition, the RKP-CMU1 is equipped with USB, RS232, Ethernet interfaces for PC connection locally and can accommodate remote warning via external GSM modem.

Using a PMBUS serial communication interface to communicate with the RCP-2000, the RKP-CMU1, as a local control centre, can accept up to four external digital inputs to monitor the operating status of other equipment or devices. With four built-in, user programmable relay contacts and LED indicators, the RKP-CMU1 can reflect the important operating status of each RCP-2000, such as AC fail, DC protection for short circuit, over-voltage, overload, over-temperature and fan fail.

With data-log and event log functionality, the RKP-CMU1 can record the status of each rack system. The default value for the data-logger is to record the working parameters of each RCP-2000 every 5 minutes (settable between 1 and 60 minutes), while the event logger can record abnormal statuses and the time of error elimination.
