P850i series inverters (dc to ac converters)

The P850i series inverters are designed based on an insulated-gate bipolar transistors (IGBT) operating at high frequency to provide clean ac power from your existing dc bus. you may order 125kVA inverters with 125Vdc iin single or three phase output. 250kVA can be provided from a 250Vdc bus. Inverters with up to 600Vdc bus are also available.

The 20 year design with the user friendly LCD menu give access to a broad range of options specially created for heavy duty applications with harsh electrical and environmental conditions. You also be operate the P850i on-line or off-line depending on your preference. The static transfer switch (STS) based on a full SCR is designed to transfer your load with no interruption and to perform in worst case short-circuit conditions to clear downstream protections due load faults.

Drip-proof, stainless steel enclosure, air-conditioned enclosures, seismic designs and special sizes to fit existing on-site infrastructure to name a few options supplied on a regular basis. Communications and special alarms can also be supplied to satisfy your access requirements.

Typical applications:

  • Pulp and paper process
  • Chemical and petrochemical plants
  • Power Generation
  • Transmission and Distribution substations
  • Oil & Gas
