Product description

PTC-Resistor-Relay Type MSF220VL For Dry-Transformers, Fan, Warning, Trip Winding and Trip Core The MSF220VL from ZIEHL industrie-elektronik is particularly suitable for monitoring of temperatures at dry transformers, when also the temperature of the core shall be measured. An intelligent control prolongs automatically the runtime of a cooling-fan, depending on the load of the transformer. Each PTC-circuit is monitored for break and short circuit. This reduces probability of false alarms. Relays in operating-current mode prevent from a trip-signal when switching on supply voltage. The device can be adapted to different applications with 4 programs: Das Gerät kann mit 4 Programmen an verschiedene Einsatzfällle angepasst werden: 1.) Fan-control - alarm - trip (winding) - trip (core) 2.) Alarm - trip (winding), trip (core) - alarm (fault) 3.) Fan-control - alarm - trip (winding) - alarm (fault) 4.) Fan-control with hysteresis T1/T2 - alarm - trip (winding) - 4 inputs for PTC - Intelligent control of fan - Automatic fan-test 1x / week - Monitoring of sensors - Test-button - Simple testing with disconnectable monitoring of break and short circuit (for 10 minutes) - LEDs for alarms, states of relays and sensors - Housing for mountion on DIN-Rail or wall-mount (option) - Mounting height 55 mm - Universal supply voltage AC/DC 24-240 V
