Application

This series starter is applicable in coal mine and around places full of explosive gas mixture such as methane, coal dust and so on. In three-phases electric fence of AC 50Hz, voltage 1140V or 660V, current 400A and neutral-point solid non-ground, it can be used as start, stop and double-speed switchover to three-phases double-speed asynchronous motor, it can control single machine or combined machine. The starter has various protection functions of under-voltage, overload, phase failure, short circuit, leakage latch and so on. There are two kinds of control mode: remote control and close control, also can change phase when machine stops.

 

Features

Protection and control system adopt imported (PLC) industrial control computer to monitor and control system, with advantages of high degree of intelligent, stable performance, reliable action and so on.

Adopts Chinese display screen to display and record operating condition, parameters and malfunction type of starter, the product has excellent man-machine conversation function.

All simulation signals are digital, with features of strong anti-interference ability, simple connection, large information capacity, reliable control, etc.

Have RS485 or CAN communication port of intrinsic safety.
