Roch RSB-1500E 1500VA Automatic Voltage Regulator (AVR)

Roch RSB-1500E 1500VA Automatic Voltage Regulator (AVR) | Dual Digital Display | Premium Series

The Roch RSB-1500E 1500VA Automatic Voltage Regulator (AVR) from the Premium Series is designed to protect and stabilize electrical devices in environments with unstable power supply. Powered by an advanced microprocessor-controlled (MCU) system, it delivers fast and precise voltage regulation while safeguarding connected equipment against over-voltage, under-voltage, overheating, overload, and electrical surges.

With a wide input voltage range of 140–260V, a 1500VA rated capacity, and a dual digital display for real-time monitoring of both input and output voltage, the RSB-1500E ensures consistent and safe power delivery at all times.

It is built with a toroidal copper transformer for efficient, stable, and low-noise operation, a 4-relay stabilization system for accurate voltage correction, zero-crossing detection for safe power transfer, and a selectable delay / timeout function to protect connected appliances during power restoration.

Additional convenience features such as a 110V assist function for compatible appliances and a built-in USB charging port make the Roch RSB-1500E a reliable and practical solution for home and office electronics, including TVs, computers, office equipment, and networking devices.
