9420 Power Supply

Brand: PR Electronics

  • Supply voltage 85...132 VAC or 187...264 VAC
  • Optional connection of backup supply
  • Approved for installation in I.S. / Ex zone 2 / Div. 2
  • Active signal output
  • Optional parallel connection
Features
  • The 85...264 VAC connection is made by using pin no. 31, 32and 33
  • The 24 VDC connection is made using the “+” and “-“connections.
  • 22 VDC ±2 VDC is applied on “DC-OK” - pin 15, 20 mA max. This signal output is referenced to –Vout (gnd.) and signals when the output voltage drops between 18 and 22 VDC.
  • Maximum 5 devices of the same type can be connected in parallel to enable increased output power.
  • The DC-OK LED is a two color LED which indicates the status of the output and enables visual evaluation of the function locally in the control cabinet.
  • DC-OK LED green – normal operation. DC-OK LED red –output failure if input mains is still present.
