Uninterruptible Power Supply (UPS) & Battery Backup Systems

Powervar UPS systems combine battery backup with power-quality protection for commercial, medical, laboratory, industrial and data-center loads. Compare isolated line-interactive UPM systems with online double-conversion UPS platforms, then confirm voltage, capacity and runtime with a specialist.

Line-interactive and online UPS topologies

Security II and GTS families use isolated line-interactive operation with true sine-wave output, while Security Plus II and Sinergy III provide online double-conversion architecture. Battery cabinets and extended runtime are application-dependent.

  • Security Plus II UPS

    Advanced power protection for mission critical applications. The Security Plus II Series is built on true online double-conversion technology paired with Powervar's proven low-impedance isolation transformer — so your equipment is continuously fed clean, conditioned, regulated power, fully decoupled from whatever the utility is doing on the other side. Voltage sags, swells, spikes, harmonics, and frequency wander are absorbed before they ever reach the load, and on a utility failure the transfer to battery is seamless because the inverter is already running the load. The result is the most reliable power and the cleanest output waveform Powervar makes, in a sleek, space-saving footprint with customizable PDUs and front access for quick, easy on-site connection and serviceability.

Frequently asked questions

What is the difference between a power conditioner and battery backup?

A power conditioner improves the quality of available utility power by addressing electrical noise, transients, common-mode voltage and some surge energy. A UPS adds stored battery energy so the load can continue operating during an outage. Conditioning does not provide outage runtime.

Do Powervar UPS systems also condition power?

Yes. Powervar UPM and UPS families provide power-quality protection as well as backup, but the exact topology varies. Security II combines line-interactive operation with a low-impedance isolation transformer, while Security Plus II uses online double conversion and an isolation transformer.

When should I specify line-interactive versus online UPS?

Line-interactive equipment can fit many distributed loads where voltage regulation, isolation and short transfer time are appropriate. Online double-conversion systems continuously regenerate the output and are often selected for especially sensitive or mission-critical loads.

Are surge suppressors the same as power conditioners?

No. A basic surge suppressor primarily limits transient overvoltage. Powervar conditioners combine surge diversion with an isolation transformer and power-line filtering, and some families also filter the safety-ground circuit.
