IEC 61238 connectors testing system



IEC 61238 connectors testing system is a scalable and modular equipment allows to test the connectors with accuracy according to IEC 61238 standard giving a solution to all the technical issues of the past. During the short circuit test the equipment delivers up to 26 kA increasing the temperature of the connectors between 250 ºC and 270 ºC.

This system consists of a charger and numerous power modules in parallel capable of generate 1300 Arms each. Every power module is composed by one unit of energy storage and a power converter.

Charging system charges modules sequentially. Once all the energy storage modules are fully charged the system releases current through each inverter to the bus bar to achieve the controlled current target at the output.

Main features

  • Based on power electronics & energy storage technology
  • Scalable; Modules of 1300 Arms
  • Fully digital closed loop controlled current output
  • Custom HMI interface
  • 20 kW power consumption
  • Time & temperature stop event
