PTC-Resistor-Relay Type MSF220VL

PublishTime：2022-07-31

The MSF220VL is particularly suitable for monitoring of temperatures at dry transformers, when also the temperature of the core shall be measured.Monitoring of core temperature is especially required in rectifier transformers because of harmonics causing heat in the core. 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.
