Automatic Voltage Switcher (AVS)

Automatic Voltage Switcher (AVS)

The Automatic Voltage Switcher (AVS) is the ultimate protection for your high-value appliances. In many regions, power fluctuations—specifically over-voltage and under-voltage—are the leading causes of motor burnouts and motherboard failures. The AVS solves this by monitoring the incoming mains power 24/7. If the voltage climbs too high (spikes) or drops too low (brownouts), the AVS instantly cuts power to your equipment.

The "Magic" of the AVS lies in its Start-up Delay. When power returns after a blackout, it is often unstable and carries "power-back surges." The AVS waits for a pre-set time (typically 30 seconds to 3 minutes) to ensure the power is clean before allowing it through to your appliance. This is especially vital for refrigerators, air conditioners, and borehole pumps, where frequent on-off switching under load can destroy the compressor.

Key Features & Specifications

·       Rating Options: Available in 13A (Plug-in) for small appliances or 30A (Direct Wiring) for whole-house or heavy-duty loads.

·       Voltage Protection: Automatically disconnects at high (e.g., >260V) and low (e.g., <185V) thresholds.

·       Microprocessor Control: Precision digital monitoring for faster response times (<20ms for over-voltage).

·       Adjustable Wait Time: User-settable delay (10 seconds to 10 minutes) to suit different appliance types.

·       Status Indicators: 5-LED display showing: High Voltage, Low Voltage, Waiting, and Good/On status.

·       Surge/Spike Suppression: Built-in protection against lightning-induced surges and electrical noise.

·       TimeSave Technology: If the power has been off for a long time, the AVS reconnects faster, reducing unnecessary waiting.
