DMR-400T

Balance minimum relays DMR-400Т and DMR-600Т aredesigned for:

- remote manual control (switching on and off) of oscillator;

- linking-up oscillator if its voltage is higher than circuit voltage, minimum 0,2÷0,3 V;

- dropping oscillator in case of reaching set value of reverse current;

- excluding possibility of oscillator of incorrect polarity linking-up;

- providing oscillator dropping or linking-up alarm.

Balance minimum relay structure:

- Rtr – triggering relay – electromagnet relay preparing BMR for work when switching on oscillator;

-Rbl – blocking relay – guarantees protection of shunt winding of balance relay while voltage drop supply ΔU> 12 V.

- Rb. – balance relay – designed for oscillator linking-up and dropping control. Polar relay with permanent magnets is used as balance relay.
