TBB AVS 30A Digital High Voltage and Low Voltage Protector Automatic Switch
TBB AVS 30A Digital High Voltage and Low Voltage Protector Automatic Switch is an Automatic Voltage Switcher built-in with a microprocessor. The AVS will switch off the equipment connected to it if the grid voltage goes outside threshold limits and will re-connect automatically when the mains power returns to normal. Re-connection takes place after a time delay to ensure the stability of the mains. In addition, the start-up delay provides protection against power-back surges which are commonly experienced after the recovery of power. Surge and spike protection are also incorporated to ensure protection against these commonly occurring events
The utility grid is a big and complex power network and has millions of kinds of devices running on it. But the utility is not always stable and reliable, and there are many electric appliances that suffered from surges and spike in grid utility sometimes. It’s considerable to protect your appliances when surges and spikes occurred. Many countries or regions are suffering from unstable grids. Voltage variation is the main reason causing electrical appliance failure. With a simple device, you can protect your appliances against the damage of an unstable grid.
TBB AVS 30A Features
- Built in micro-processor control
- Over voltage and under voltage protection with built in time delay
- Switch off voltage threshold and time delay adjustable
- LCD display protection voltage level
- Manual switch on/off when needed
