Description

The Phoenix Contact MCR-PS-24DC/24DC/200 (order number 2766821) is an electrically isolated DC/DC converter in the MCR signal conditioning series, designed to supply 24 V DC auxiliary power within MCR measurement and control technology cabinets. This part is also cross-referenced under the alternate format MCRPS24DC24DC200. Note: this part number has been discontinued by the manufacturer. Refer to manufacturer documentation to confirm compatibility with your specific application.

The converter accepts an input voltage range of Twenty (20) V DC to Thirty (30) V DC, drawing up to 380 mA on the input side, and delivers a regulated output of 24 V DC at up to Two Hundred (200) mA — yielding a nominal output power of approximately 4.8 W. Output voltage regulation is ±5% with a ripple voltage of 250 mV peak-to-peak. Input-to-output electrical isolation is rated at 2.5 kV AC at 50 Hz for one minute. The unit mounts on standard DIN rail.

The MCR-PS series DC/DC converters are used to regenerate 24 V DC supply voltage at the end of long cable runs, create galvanically isolated sub-circuits within a control panel, or provide a dedicated power source for MCR signal conditioner modules without relying on the main 24 V bus.
