World Part Supplier Inverter 3 Phase, 4.5 KW, Sine Wave is an exclusive design for hard and sever applications. We designed it based on the requirements of one of our clients.

Few years ago, one of our valued clients asked for new design on its existing air conditioner system. Our engineering department started investigating on the inquiry. Based on the existing systems of client fleet, we decided to manufacture a system that can be interchangeable with DPG (Dayton-Phoenix Group) air conditioner inverter.



Our inverter is combined of two parts: Compressor Inverter P/N: WPS-5001C and Blower Fans Inverter P/N: WPS-5001F.

Those two segments link together by mean of flat cable. Both parts have their own control system and check itself and under control circuits before running.



You can have access to events by connecting to Event Logger by mean of WPS-AC-EL Software.

You will have access to all recorded events such as errors, corrections, temperatures, operating mode etc.


Our designed inverter can replace DPG (Dayton-Phoenix Group) air conditioner inverters P/N: S2805575, S2805576 and interface board P/N: S22109767



Short technical explanation of this production is:

  • Input voltage: 64-74 VDC
  • Output Voltage: 55 VAC, 3 Phase, Sine Wave, 50Hz
  • Power: 4.5 KW Nominal, 6 KW
  • Under Voltage and Over Voltage Control
  • Over Current Controller
  • Inside and Outside Temperature Controller
  • Smart System Controller
