## Summary description

The LSiS AS-12M coil surge suppressor is designed for use with contactors to protect control circuits from voltage spikes. Operating within an AC voltage range of 24-48V, this module effectively suppresses transient surges, ensuring reliable operation and extending the lifespan of electrical components in industrial automation systems.

## Long description

The LSiS AS-12M coil surge suppressor is a specialized component engineered to safeguard control circuits by mitigating voltage spikes generated by contactor coils. Designed for industrial automation environments, this module operates within an AC voltage range of 24-48V, providing a stable electrical environment that prevents damage to sensitive electronic controllers and relays.
Advantages
This surge suppressor offers significant benefits by effectively clamping transient voltage surges that occur during the de-energization of inductive loads. By minimizing electrical noise and interference, it helps maintain the integrity of control signals and prevents premature wear of contact points. Its compact design allows for seamless integration into existing control panels, contributing to the overall longevity and reliability of the entire electrical system.
Suitable for
Industrial automation control panels
Motor starter circuits
Relay and contactor protection
Systems utilizing 24-48V AC control voltages
This device is not intended for use in DC circuits or applications where the control voltage exceeds the specified 24-48V AC range. It is also not suitable for high-power main circuit protection, as it is specifically designed for low-voltage control coil suppression.
Key specifications
Operating voltage: 24-48V AC
Function: Coil surge suppression
Compatibility: LSiS contactors
Application: Transient voltage protection
To install the LSiS AS-12M, ensure the power supply to the control circuit is completely disconnected. The module should be mounted directly onto the designated terminals of the compatible contactor. Once securely attached, verify that the connections are tight and that the module is properly seated before restoring power to the system.
What to consider before purchase
Verify the control voltage of your contactor coil matches the 24-48V AC range
Ensure compatibility with your specific LSiS contactor model
Confirm the physical space available in your control cabinet for the module
For optimal performance and safety, always inspect the surge suppressor during routine maintenance intervals. If the module shows signs of physical damage or if the control circuit experiences frequent unexplained faults, test the suppressor and replace it if necessary to ensure continued protection of your automation equipment.
