Green LED indicator lamp

If the lamp in on, it indicates the relay picks up, that is, the output terminals A is connected to C.

If the following conditions appear, the LED lamp will go out and the relay is switched off, that is, terminal A is disconnected from C.

1.        The phase sequence of output terminals R, S and T is connected incorrectly;

2.            Over-voltage, under-voltage, phase-lacking or imbalance happens.

Main use of product:

It is mainly suitable for central air conditioner, cabinet air conditioner over 5HP, elevator and large-scale mechanical and electric products.

Characteristics of product:

This product can switch off some control coil of the electric appliances in case the phase order is in confuse in the network or phase is lack or the voltage is higher than 460VAC and lower than 342VAC thus to reach the protection purpose.

Characteristics of protection：

Dynamic phase-lacking protection and static phase-lacking protection, which starts to work if one phase opens when the protected equipment is in operating course or un-operating state. The yellow indicator lamp goes out.

   Error-phase protection: It is a protection method preventing T, S and R three-phase power supply connecting incorrectly. It can work instantly and the yellow indicator lamp goes out.

Over-voltage protection: means the voltage of the protected circuit is lower than the set value; the LED        indicator lamp goes out.

Performance characteri stics:

The monitor can exert its protection function wholly and in any climate for a long time. The power≤25W;

This product has pass CE Certification.

Work characteristics:

If three phases T, S and R are in a correct connection, the yellow indicator lamp is on and the relay picks up; If the phase sequence is connected incorrectly, the yellow indicator lamp goes out

If three phases T, S and R, or any phase loses, the yellow indicator lamp goes out. When the voltage is normal, the yellow lamp is on and the relay picked up.
