OTB-EX Series 10-40KVA

OTB-EX Series

Online UPS Low frequency 10KVA to 40KVA (Three Phase in and Single phase out)

OTB-EX series Online UPS 10KVA-40KVA is a true online double conversion Three phase in and single phase out lowfrequency UPS, Adopting the online dual-change topological architecture design, the AC/DC input has a harmonious inhibitor, which eliminates various interference of the grid. IGBT power module and output isolation transformer, so that the output of UPS is a pure sine power with a steady frequency voltage, UPS has the characteristics of strong load capacity, good load compatibility, municipal electric input voltage, wide frequency range, no switching time output, excellent generator, and compatible matching.

  • The double-conversion online design makes the output of the UPS a pure sinewave power supply with
    frequency tracking, phase-locked voltage regulation, noise filtering, low distortion, and no interface from the
    power grid providing more comprehensive and perfect protection for user equipment.
  • DPS (Digital signal Processors) technology
  • Output zero conversion time to meet the high standard requirements of precision equipment for power
    supply.
  • Standard isolation transformer to effectively respond to load transient impact.
  • Wide input voltage ranges up to 165 ~ 275 VAC, avoid frequency switching to battery mode, which adapts to
    areas with harsh environments
  • Wide input frequency range, ensure all types of fuel generators connected work stably. High overload
    capability (up to 150%)
  • Some units can be directly connected in parallel, increasing the scalability of the system. The parallel system
    can share a group of backup batteries.
  • Cold start and mains start function.
  • Superior protections (surge, short-circuit, overvoltage, under voltage, overcharge, reverse battery
    protection, etc.)
  • Advanced communications: RS232 port (Standard), USB, SNMP, dry contacts, and RS485 (Optional)
  • Other options (input isolation transformer, bypass isolation transformer, and harmonic suppressor).
