DZQⅡ- CD-103 summary
The inverter voltage of low-voltage motor is suddenly reduced to prevent the abnormal shutdown of motor caused by instantaneous fluctuation and voltage loss of power supply.
DZQⅡ- CD-103 performance
A pair of operation signals of DZQⅡ- CD-103 controller output the normally open dry contact (run signal), which is used for short-time locking of the state signal transmitted by the controlled contactor to DCS, PLC, VVVF and other digital control equipment, so that the above-mentioned equipment will not interlock during the "power swing". Because the "power swing" voltage flicker time is very short, it is only a disturbance process, so the instantaneous forced locking will not bring adverse effects to the equipment and production safety.
