Operating system
Magnetic Latching Relay is a kind of high-power relay, of which the contact
condition is maintained by the magnetic force from permanent magnet. When the load
need to be open or closed, positive and negative dc impulse voltage will drive
the coil,so that relay can complete the state transition between opening and closing
instantly. And then, the coil doesn’t need electricity any more, only by the magnetic
force of permanent magnet, its condition can be maintained.
electrical protection relay Advantages
1.Only need pulse excitation and can be single or double coils working.
2.Small volume and PCB installation.
3.Low power consumption and strong load capacity.
4.Security, reliable and long working life.
