Discover the Stability of Qoltec’s 500VA Pure Sine Wave UPS

Uninterrupted power for monitoring systems, tools, heaters, pumps, and many more low-power devices.

The Qoltec 500VA / 350W Pure Sine Wave UPS provides reliable backup power during mains outages, automatically switching to battery mode to protect connected devices and keep them operating without interruption. Built from high-quality materials, it ensures stability, safety, and long-term performance.

Key Features

• Pure sine wave output – stable, interference-free energy for maximum device protection

• Line-interactive design with AVR – automatic voltage regulation for consistent power supply

• Constant phase – phase remains steady regardless of power source

• Dual conversion technology – AC → DC → AC for the highest quality output

• Multiple protections – overload, short circuit, over/undervoltage, overheating, reverse battery connection

• Integrated LED display – clear real-time monitoring of parameters and alerts

• Flexible compatibility – ideal for monitoring systems, LED lighting, fans, gate drives, pumps, CO heaters, and other low-power devices

Protection & Monitoring

The UPS is equipped with an LED display and audible alarms that notify about:

• low battery voltage,

• battery discharge,

• overload (<120% and >120%),

• overheating,

• error status.

By following the included manual, you can ensure safe, continuous operation of connected devices for years.
