MSF 220 VU

Ziehl

The MSF 220 V is particularly suitable for the temperature monitoring at dry transformers. 3 PTC-circuits with different nominal response temperatures (NRT) can be connected to this unit, one for controlling a fan (forced cooling) and two for alarms. Each PTC-circuit is monitored for break and short circuit. This reduces the probability of false alarms.

  • 3 PTC-circuits
  • MSF 220 VU for universal supply voltage AC/DC 24-240 V
  • intelligent control of fan (relay K0, 1 normally-open contact)
  • ALARM 1 in closed-circuit current mode (relay K1, 1 change-over contact) for pre alarm. Signals also error in any sensor and interruption of supply voltage.
  •  ALARM 2 in operation current mode (relay K2, 1 changeover contact). No signal when switching on and off the supply voltage.
  • all output relays potentially separated from each other.
  • monitoring of sensor lines
  • TEST-button (stop possible before ALARM 2)
  • Simple testing with disconnectable monitoring of break and short circuit  (for 10 minutes).
  • LEDs for ON, sensor error, Fan, ALARM 1 and ALARM 2
  • UL recognized component
  • plug-in terminals
  • housing for mounting on DIN-rail or wall-mount
  • mounting height 55 mm
