Current Source E143

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

The Current Source E143 is a 3A constant current generator. Its main purpose is to extend the output current of the Battery Charger E1402 up to 6A. It can be used also independently by the consumers of  3A current with the voltage up to 20V.  The modules hermetical enclosure makes it resistant to field conditions.


  • Extending the output current of Battery Charger E1402 up to 6A. It does not include any charging regulator, instead of that it uses the regulator in the E1402 which takes into account the environment temperature andthe charge rate of the battery. Therefore, it employs  simpler circuitry of lower cost.
  •  Using mains supply of ~220V 50Hz as energy source
  •  Protection of the power supply system against the lightning discharges and other noises by dedicated input filters (optional)
  •  Hermetized design, the sealed enclosure is filled with Nitrogen gas

Connecting  the  E143 module to the Battery Charger E1402
