LightWave LW‑UPS‑850 3 PIN UPS (850 VA / 480 W)

LightWave LW‑UPS‑850 is a line-interactive 850 VA (approx. 480 W) backup power solution designed for home and small office environments. Featuring automatic voltage regulation, built-in surge protection, battery health warning, LED status indicators and audible alarms, it delivers stable power to desktop computers, routers, CCTV systems and peripherals during outages or voltage fluctuations.

Product Features

automatic voltage regulation with avr

Boost-and-buck AVR actively corrects high or low input voltage without switching to battery, enhancing battery lifespan and protecting connected devices.

early warning battery failure diagnostics

Built-in battery health monitoring provides early notification when battery replacement is needed, enabling timely preventive maintenance.

led indicators for real-time status

LEDs display key conditions such as mains operation, battery mode, overload and battery replacement alerts, simplifying diagnostics.

audible alarms for key events

Warning sounds alert users during transitions such as switching to battery mode or overload conditions.

simulated sine wave output

Provides stable simulated sine wave output during battery operation, suitable for typical office and home electronic equipment.

cold-start capability

Allows the UPS to power on and supply critical devices even when AC mains power is absent.
