DC / AC Inverters

Inverters developed by SUPSONIK, S.L. are compact and reliable, designed to generate a stable and clean sinusoidal voltage to supply critical loads:

  • Telecommunications
  • Computer systems
  • Naval sector
  • Industry sector
  • Electrical substations
  • Hospitals

The function of a DC / AC Inverter is to convert direct current voltage from a group of batteries or a rectifier system into an alternating voltage of constant frequency and amplitude.

The equipment is designed in 19 "rack format, available in several models differentiated by their nominal power, frequency and input and output voltages. Due to the modular structure, different configurations are obtained for the full equipment:

  • Wide range of input voltages - 24, 48, 110, 220 Vdc
  • Single-phase output voltage of 115, 127, 230, 254 Vac
  • Three-phase output voltage of 200, 220, 400, 440 Vac
  • Output Frequency 50, 60, 400 Hz

Other advantages of modular equipment are the ease of maintenance and replacement of modules, availability of the reserve module for N + 1 configuration, distribution of output currents for parallel operation. The modular structure allows high MTBF and low MTTR values to be reached.

Main features of DC / AC Inverters:

  • 19´´ Rack format 19 (other formats available)
  • Low harmonic distortion sine wave
  • Wide range of input and output voltages (single-phase / three-phase)
  • Availability of output frequencies 50, 60, 400 Hz
