VSAM for AC Contactor Protection

VSAM can effectively prevent the contactor from tripping due to voltage drop/power outage caused by shaking, keeping the contactor engaged during shaking, avoiding tripping during shaking, and ensuring the normal and continuous operation of the equipment.
VSAM has convenient wiring, easy installation, simple operation, high precision, and a wide range of anti shaking time. It can be used for any type of AC220V, AC380V contactor.

VSAM anti oscillation protector can also complete the detection and synchronous tracking function of the mains voltage, achieve frequency and phase locking of the mains voltage, and can also detect the instantaneous value of the mains voltage in real time, ensuring that it switches to the inverter output of VSAM within milliseconds when the mains power fails, ensuring that the contactor and relay do not trip, and can ensure the continuous operation of the frequency converter and soft starter.
VSAM is widely used in fields such as petroleum, chemical, metallurgical, mining, power, environmental protection, municipal, and military industries.

product details

Functional features

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.
