Category
Industrial UPS

When the protected process is a power plant, a substation or a steel line, the UPS is specified for worst-case electrical abuse — and that is exactly what the GX series is engineered to deliver: power-frequency online conversion behind an isolation transformer, with overload, surge and interference tolerance that high-frequency designs cannot match. Capacities from 6kVA single units to 600kVA systems, in high-voltage (220–240Vac) and low-voltage (100–120Vac) output versions.

Key Features

  • Power-frequency topology with isolation-transformer output — galvanic separation and brutal overload tolerance
  • Wide range: 6kVA single units up to 600kVA systems
  • LV versions with 100/110/120Vac output for low-voltage industrial sites
  • High anti-interference, lightning protection and surge resistance
  • Strong overload capacity for inrush-heavy industrial loads
  • Engineered for electric-power environments: wide input window, generator and DC-system compatibility

Applications

Power plants & substations

Relay protection, control and communication systems demand the robustness only power-frequency designs guarantee.

Steel, mining & chemical

Inrush-heavy loads and dirty supply stop high-frequency UPS; the GX shrugs them off.

Low-voltage industrial sites

LV versions deliver 100–120Vac output for sites standardized on low-voltage control power.

FAQ

Why choose power-frequency over high-frequency?
Overload tolerance and isolation. Transformer-based designs ride through inrush and short circuits that trip high-frequency units, and the transformer adds galvanic separation. In exchange, expect slightly lower efficiency and a larger footprint.
What is the largest configuration?
The GX33 line scales to 600kVA. Larger sites combine units in parallel — send your single-line diagram for a proposal.
