Applications

Backup Power / Critical Power (UPS)

Key features

  • Double-conversion online design with zero output transfer time.
  • DSP digital control for a stable, reliable system.
  • Active power factor correction (PFC) close to 1, reducing grid pollution.
  • Ultra-wide input voltage range — accepts voltages as low as 210V without switching to battery power.
  • Automatically adapts to 50/60Hz, compatible with fuel generators.
  • LCD + LED real-time display of UPS operating status.
  • Self-diagnosis function detects hidden faults.
  • N+1 parallel redundant design, up to 3 units in parallel, for higher system reliability.
  • Comprehensive protection: over/under-voltage, overload, short-circuit, temperature and battery overcharge.
  • Efficiency up to 90%, reducing power loss.
  • Standard RS232 communication interface for remote monitoring.
  • Cold-start capability directly from battery.
  • Input phase-sequence protection prevents incorrect phase wiring from powering on.
  • Automatic recovery and reconnection when utility power returns, with unattended battery charging.
