MEAN WELL RCP-MU series: Power control and monitoring unit - RCP-MU

Description

RCP-MU — Power control and monitoring unit

MEAN WELL RCP-MU is a 1U, 19-inch rack-mounted control and monitoring unit for up to three RCP-1000 power supplies. It displays each power unit’s output voltage, output current and internal temperature, provides front-panel ON/OFF control and ±10% voltage trimming, and reports AC, DC and temperature alarms through LEDs and potential-free relay contacts. Standard voltage selections are 12, 24 and 48 V; this controller does not provide an RCP-1000-rated power output.

Product scope and monitoring

Product function Power control and monitoring unit for the MEAN WELL RCP-1000 rack-power series. One RCP-MU controls and monitors up to three RCP-1000 units; it is not itself an RCP-1000 power-output module.
Rack and voltage compatibility 1U low-profile, 19-inch rack format. Standard monitored RCP output-voltage selections are 12, 24 and 48 V. The 66 V selection is reserved for specially custom-made RCP-1000 models.
Monitoring inputs I²C signals carrying AC OK, DC OK and overtemperature alarm information for each RCP-1000 unit, together with the output voltage of the RCP-1U rack.
Digital meter displays Front-panel digital meters display DC output voltage, output current and internal temperature for each monitored RCP-1000 unit, in the PSU1, PSU2 and PSU3 display sections.
Display resolution and tolerance Resolution and tolerance depend on the controlled RCP series. The RCP-MU catalog does not specify one fixed numerical accuracy for every connected power unit.
Control outputs Remote ON/OFF and output-voltage trimming for each RCP-1000 unit. The controlled unit can be switched ON or OFF using the RCP-MU front-panel controls.
Output-voltage adjustment The front-panel potentiometers trim the controlled RCP-1000 output voltage by ±10%. The output-voltage lock can disable or enable this adjustment; the monitored voltage is not a rated power output of the RCP-MU.
Alarm contacts and rating Potential-free relay contacts for AC Fail, DC Fail and overtemperature alarm; contact rating 30 V DC, 1 A.
Alarm action AC input failure: the corresponding relay opens and its LED lights. DC output failure: the corresponding relay opens and its LED lights. When temperature exceeds the applicable limit: the temperature-alarm relay opens and its LED lights.
Front-panel indicators Each monitored power-unit section has AC Fail, DC Fail and Temp Alarm indications, alongside VOLTS, AMPS and TEMP displays.

Supply input and operating conditions

Supply voltage range 90–264 V AC or 127–370 V DC. These are the supply inputs to the control/monitor unit.
AC frequency 47–63 Hz.
AC input current 0.35 A at 115 V AC; 0.2 A at 230 V AC, typical.
Inrush current 30 A at 115 V AC; 50 A at 230 V AC, typical.
Operating environment Operating temperature: −20 to +60°C. Working humidity: 20–90% RH, non-condensing.
Storage environment −40 to +85°C; 10–95% RH, non-condensing.
High-altitude conditions Above 2000 m, the catalog gives ambient-temperature derating of 3.5°C per additional 1000 m for fanless models and 5°C per additional 1000 m for fan-equipped models. Confirm the applicable cooling category for the supplied unit; the controlled RCP-1000 and the RCP-MU are separate devices.
Vibration 10–500 Hz, 2G; 10 minutes per cycle and 60 minutes each along the X, Y and Z axes.
General measurement conditions Unless otherwise stated, parameters are measured at 230 V AC input, rated load and 25°C ambient temperature.
Rear-panel label reference The illustrated rear label shows 100–240 V AC, 50/60 Hz and 0.35–0.2 A. The specification table gives the full operating input range and the typical-current test voltages stated above.

Connectors and alarm wiring

AC input terminal assignments Terminal 1: FG (protective earth); terminal 2: AC/N; terminal 3: AC/L. Follow the rear-panel drawing and actual markings.

24 V model selection Model Select switches 1/2/3: OFF/ON/OFF.
48 V model selection Model Select switches 1/2/3: ON/OFF/OFF; factory original selection.
