AVR 1000V Watts AC Automatic Voltage Regulator

Capacity: 1000VA (Volt-Amps) or 1000W (Watts), according to some product listings. 
Input Voltage Range: A wide range like 100-260V allows the AVR to handle various voltage levels. 

Output Voltage: Offers both 220V and 110V output options, sometimes with separate sockets. 

Protection: Overload protection, high/low voltage cut-off, and fuse protection are common features. 

Time Delay: Some AVRs include a delay on/off function to protect connected devices from sudden voltage changes, especially after a power outage. 

Display: Digital displays are often used to show input and output voltage readings. 

Cooling: Some models may include a cooling fan for enhanced performance. 

Relay Type: Some AVRs are relay-type, meaning they use relays to switch between voltage regulation modes.
