ME544 power supply - Inor

ME544 power supply - Inor

4-channel Power Supply for 2-wire Transmitters

ME544 has four galvanically isolated supply channels for 2-wire transmitters.
The output voltage for each channel is 25 VDC.
Each channel is short-circuit protected and has a current limitation to protect measurement circuits from damage caused by short circuits or other faults.
ME544 cuts the risk for measurement errors caused by earth potential differences with a number of 2-wire transmitters in the same measurement system.

  • 4 galvanically isolated supply channels for 2-wire transmitters
  • 25 V stabilized supply voltage
  • Short-circuit safe
  • Current limited to ~35 mA
  • Available for AC or DC power supply
  • Compact mounting on DIN rail
  • Plug-in screw terminals
