AC Power Converter E174

We regret to inform you that this product is DISCONTINUED; please find our current products here

The AC Power Converter E174 is intended to convert ~220V/50Hz mains supply to 140V DC voltage of up to 1.4kW output power, which is needed for the 1000W lighthouse control system E602. It delivers a regulated output (100…150V)±3% and provides high efficiency of conversion over wide  range of load currents and environment temperatures

  •  Normally, when the power of ~220V mains  is sufficient, the DC power to the Power Flasher E175 and to the 1000W lamp will be delivered by E174 
  •  If the  energy from the mains  is interrupted or insufficient, then the Power Flasher E175 and 1000W lamp will be supplied by  the buffer battery
  •  When the ~220V mains returns, then the E174 charges the buffer battery and supplies the energy also to the Power Flasher E175 and the lamp
  •  Optimal control of battery charging when ~220V mains supply returns
  • Monitoring by the embedded microprocessor unit of all input/output voltages, temperatures and setting the level of output voltage
  •  Sending status information to the E602  over the local area network (Echelon LON)
  •  Protection  of the output against shorting and overloading
