AC Surge Protection for Home Electronics

Functions:

Surge Protection features guarantee defense against hazardous high-voltage electrical surges that occur during lightning attacks and power variance by safeguarding air conditioner units alongside other connected electronics from electrical destruction.
Automatic link disconnection happens when the voltage reaches beyond safe boundaries thus stopping dangerous overvoltage from affecting connected devices.
The surge protector integrates power filtering capabilities that clean power supply noise to enable the smooth efficient operation of air conditioners alongside other appliances.
This device possesses durable materials and components that make it suitable for extended protection when placed in surge-prone areas for continuous operation.
The device features a simple design that allows easy setup and works well for home and business environments.

AC Surge Protection for Industrial Equipment

Applications:

This surge protection solution fulfills the needs of air conditioners together with HVAC systems and powerful electrical appliances that need protection from surges.
Such devices provide stable protection to sensitive equipment within unstable or fluctuating power supply areas.

Technical Specifications:

This device supports voltage between AC 220V-240V for power supply systems yet each specific model may have its own nominal range.
This device accepts current ratings from 16A up to the maximum available on each model.
This product provides dual surge protection capacity with capabilities to handle surge currents reaching 6000A, 9000A, or over.
The device disconnects the power supply instantaneously through a swift response time so it can safeguard equipment from surges.
