general information
The resistor-relais type MSF 220K is particularly qualified to survey dry transformers. It’s a low-cost version without the loss of survey safety and reliability. The relais for the tripping (alarm 2) won’t show an error message during the powe activation. There is no need for a timerelais that is connected in series and approaches delayed. Because of this , devices can be installed even if the control voltage is from the observed transformer. With the integrated “test”-switch, devices and downstreamed systems can be observed easily. Additional terminals allow a comfortable pulling of the control voltage to the relais K1 and/or K2.
