Description
The AVR consists of three identical single-phase regulator units that work together to monitor and adjust the output voltage within a narrow range for your equipment’s safe and efficient operation.

The AVR3x50PTZ has a very wide input voltage range of -30% to +22% making it suitable even in areas with a very erratic supply. It maintains an output accuracy of ±4%, which makes it ideal for even the most sensitive equipment.

The AVR uses isolating transformers to isolate the potential voltages from the source to the load, with no input neutral, providing protection against grounding issues and preventing electric shock. The transformers also reduce electrical noise and interference and offer surge and spike protection.

The AVR3x50PTZ range is fully electronic and has no moving parts, which makes it highly reliable and accurate with fast response times. It is enclosed in an IP44 enclosure, making it suitable for installation in outdoor and harsh environments that are susceptible to dust and water splashes.

Overall, the AVR3x50PTZ is a highly reliable and accurate voltage regulator designed to provide safe and efficient equipment operation even in the harshest voltage and environmental conditions.

Equipped With
- Automatic Voltage Switcher to protect against very low and very high voltage
- Input Circuit Breaker protecting the AVR
- Output Circuit Breaker protecting the load in the event of a short circuit or overload
- Isolating Transformer
- Digital Meters for Input and output voltage, output current & frequency
- Changeover Switch to power the load direct from the utility supply
- Class I & II Surge Protection Device
