EV Charging Station Tester – Metrel – MI 3152 XC

The most sophisticated series of multifunctional measuring tools from Metrel is made exclusively for industrial testing and includes a whole section on testing for electric vehicle charging stations. its user-friendly touch screen interface, which includes a memory organizer and fully customizable AUTO SEQUENCEs, and ergonomic design.

  • Connects directly to charge points without opening the box.
  • Connects like an electric vehicle connection; so tests the whole system.
  • Simulates the electric vehicle status: all at the turn of a switch.
  • Simple connection to the charge point via a type 2 EV plug, and to the tester using the BS1363 socket or all three phases can be accessed using standard 4 mm connections.
  • The A 1532 can be used with any installation tester, however, optimum performance is achieved with Metrel Multifunction Testers.

You may service and test EV Chargers installed in public and commercial places for electrical safety and compliance with AS3000 standards with this equipment for testing electric car charging stations. Only the MI 3152 XC supports functional tests, including AUTO SEQUENCE®, which calls for the 1532 Adapter.

The installation, operation, and safety of the EV charging station as well as all other aspects of electrical installations can be examined using the Metrel MI3152 XC Multifunction Installation Tester. With the push of a button, it can test EV RCDs, has EVSE AUTO SEQUENCES, and functions that allow the user to examine each component of EV charging stations state-by-state.
