Semidan Power 919 Uninterruptible Power Supply (UPS)

The Semidan Power, SP 919 UPS system, handles the low output range of 0.2-5.0 kVA. In the SP 919 the charger, battery and static inverter are built together in such a way that a completely uninterruptible supply is achieved (online).

Characteristics
  • The SP 919 can be fit into a 19” rack module
  • Pure sine wave voltage ±1% and frequency ± 0.5% at the output
  • Distortion less then 5%
  • Protected against short circuit
  • Start with full load
  • Excellent dynamic response
  • Forced cooling/conventional cooling
  • Uninterruptible supply
  • Maintenance free, long life time
  • Easy service accessibility
  • Economic in use
