- Selectable input voltage range for household appliances and personal computers
- The time delay function eliminates transients that can affect connected equipment
- Microprocessor control guarantees high reliability

The PowerWalker AVR SIV series are automatic voltage regulators with selectable input voltages from 150 V to 270 V AC or wide 110 V to 280 V AC. The output voltage is ensured within the permissible limit of +/- 10% (between 207 V and 253 V AC) by means of gain and buck stabilizers. A built-in thermal sensor provides overheat protection and recovery while eliminating abnormal situations.
The device operates in the following modes, depending on the input voltage:
- Input 252 V ~ 270/280 V AC: buck mode -10% relative to the input voltage
- Input 207 V ~ 252 V AC: normal operation
- Input 173 V ~ 211 V AC: first boost + 20%
- Input 110/150 V ~ 178 V AC: second stage + 40%
