This is a true double-conversion online UPS, but it’s built around low-frequency inverter technology—which means it handles tough loads differently than high-frequency units. If you’re running motors, transformers, laser cutters, or anything with a heavy inrush current, this one’s got the muscle to start them and keep them running.

Output power factor is 0.9, and the overload capacity is genuinely useful: 125% for 10 minutes, 150% for a full minute. That’s not just a marketing number—it gives you real breathing room when equipment kicks on or when a temporary overload happens.

It handles 100% unbalanced loads without breaking a sweat, which matters when you’re powering three-phase gear that doesn’t draw evenly across phases. You can also set it up for dual power supply if you need redundant mains inputs, and if you need more capacity or redundancy, N+1 parallel configuration is available.

The DSP-based control is fully digital, so everything stays tight and consistent. Intelligent battery management helps get more life out of the batteries, and it plays nice with generators—no nuisance transfers when the generator sags or surges.

Protections are thorough: fast-acting fuses on DC, redundant fans, temperature sensors, and even protection for the fans themselves. It’s designed to keep running even when conditions get rough.

Cold start is standard, so you can fire it up from battery even if the grid is dead. Efficiency sits above 92%, which is solid for a low-frequency design focused on raw capability rather than chasing the highest efficiency number.

For communication, you’ve got RS232, SNMP, and GPRS options—so whether you’re in a local server room or monitoring a remote site, you can stay connected.

Typical places you’ll see this one: large IDC rooms, industrial automation lines, bank and securities settlement centers, semiconductor production, laser cutting, and even highway or railway tunnel lighting systems where metal halide lamps need clean, stable power.
