Thông tin sản phẩm

- 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
