Description

1. Working principle

DM- series electronic arcing is widely used in mechanical manufacturing, chemical industry, light industry, switches, switch circuit, cnc machine tools, computer control CNC automatic production line and CNC machines and equipped with all kinds of electrical control equipment of speed regulation system. In the numerical control system, various kinds of its periphery lines have contactor, relays and motor, and the final object is the motor control system of contactor instantly and contacts, often because of contacts, arc, serious cause disturbance to the control system, the system of the waveform distortion occurs. At the same time, the open and close contacts occur when the voltage spark, cause loss of contact surface oxidation, deformation, and damage the contactor. If the object is a digital control circuits or systems by computer program control, so the original program will completely destroy control system doesn't work, or even damaged circuits.

2.Applications

DM series generally parallel in both ends of the DC circuit,such as DC contactor, relay coil, solenoid valve coil.It is always happened that reverse voltage comes from both ends of load feeding back to power supply ,in that occasion other circuits are disturbed.At this time,DM series are used to eliminate all impacts to the power supply and control loop
