Tronic Digital Automatic Voltage Switcher (AVS 30)

The Tronic Digital Automatic Voltage Switcher (AVS 30) is a heavy-duty power protection solution engineered to protect residential, commercial, and industrial electrical systems from unstable grid conditions. Designed for high-capacity applications, this advanced voltage switcher continuously monitors single-phase power and automatically disconnects supply during dangerous electrical faults such as over-voltage, under-voltage, surges, and neutral loss. With adjustable voltage thresholds, configurable delay timers, and a real-time digital display, the AVS 30 provides intelligent and reliable protection for sensitive appliances, cooling systems, pumps, and large electrical installations.

Product Features

Advanced Over and Under Voltage Protection

The AVS 30 automatically disconnects power whenever voltage exceeds safe operating limits or drops below acceptable levels, protecting connected appliances from electrical damage caused by unstable grid supply.

Intelligent Power Back Surge Defense

Following a blackout or power interruption, the device remains disconnected for a controlled delay period to prevent damage caused by sudden surge spikes during grid restoration.

Digital LCD and LED Display

The integrated digital display provides real-time voltage monitoring and operational alerts, including WAIT, OK, and FAULT indicators for easy system status tracking.

Adjustable Voltage Threshold Settings

Users can customize both high and low voltage cut-off ranges, allowing precise configuration based on the requirements of connected appliances and local power conditions.

Configurable Delay Timer

The built-in delay timer can be adjusted from 10 seconds to 10 minutes, preventing rapid power cycling and ensuring stable reconnection after electrical disturbances.

Neutral Loss and Surge Protection

The device protects appliances against neutral wire faults and absorbs sudden voltage spikes with integrated surge suppression technology.

Heavy Duty High Capacity Design

With a 30 Amp rating and support for up to 7200W loads, the AVS 30 is suitable for demanding electrical systems including commercial cooling units, air conditioning systems, pumps, and whole-house installations.

Durable Industrial Grade Construction

Built with a high-impact PVC casing and high-capacity brass terminals, the unit is designed for long-lasting durability and secure electrical connections.
