Three Phase Motor Reversing Module KMRT-H

KMRT-H, the functional motor reversing module, is specially designed for the control of three-phase AC asynchronous motor with the built-in input logic interlock circuit and the built-in turn-on delay circuit and the switching time over 80ms, which can prevent the damage to the module caused by the delayed turn-off of the SCR due to misoperation;

KMRT-H has the built-in functions as follows: the power phase absence protection function, the power phase absence feedback indication function and the automatic phase correction function (the power phase absence feedback indication function and the automatic phase correction function are optional therein).

When the three-phase power supply has the phase absence problem, the module will be turned off without any output voltage, and the motor will stop working, meanwhile the module can generate the isolated passive feedback signal and can illume the malfunction indicator lamp on the module.

When the phase sequence of the three phase power supply changes, the module can correct the power phase sequence automatically and ensure that the positive and negative rotation keeps the same direction.

This module has two output current ratings 25A and 50A, with the output voltage range 48~530VAC, meanwhile a dichromatic LED for indicating the operating status is equipped. It is widely used for the three-phase motor control in the heavy chemical industry and the electric actuating mechanism control, of which the typical applications are the blender control, the steam valve control, the flow control and the air door control etc.
