Industrial Frequency UPS — Three Phase Online UPS 10–400kVA
Industrial frequency UPS systems are three-phase online double-conversion units built with an output isolation transformer and IGBT rectifier, designed for harsh industrial environments and heavy loads. Rated 10–400 kVA with 380/400/415V three-phase input and output, they provide galvanic isolation, high overload capacity, and full parallel redundancy (N+1) for critical process loads.
Key Features
Online double-conversion topology with output isolation transformer
Three-phase 380/400/415V input and output, 10–400 kVA

N+1 parallel redundancy with automatic load sharing
Wide input voltage and frequency tolerance for unstable grids
Applications
- Industrial process control and DCS
- Petrochemical and mining operations
- Manufacturing lines and motor drives
- Data centers and telecom exchanges
Selection Guide
Isolation
Specify an output isolation transformer for galvanic isolation and grid robustness.
Redundancy
Add N+1 parallel units for critical process availability.
Battery runtime
Size the external battery bank for the required autonomy at full load.
- Frequently Asked Questions
Why choose an industrial frequency UPS over a high-frequency UPS?
Industrial frequency UPS uses an output isolation transformer, giving galvanic isolation, higher overload capacity and better tolerance of harsh grids and motor loads — preferred for heavy industrial and process applications.
Can multiple units run in parallel?
Yes, N+1 parallel redundancy with automatic load sharing increases availability; if one module fails, the others continue to supply the load.
What overload capacity is typical?
Industrial frequency UPS commonly supports 125–150% overload for 1 minute, which is important for motor and inrush starting currents.
