Products Advantage
Realize delay free linkage with PLC signals, stop as needed, and start as needed.
VSAM accurately judges the power supply status in real time. It operates when the power supply voltage reaches the set value and is in a hot standby state when the power supply voltage is normal.
Contactor control coil demagnetization protection function.
Output 220V AC power supply without damaging the contactor coil.
Parallel access system;
Service life>15 years.
