• Communication interface: RS232, CAN-BUS

Not every verification job needs a 60 kW load bank. On sites with a mix of AC chargers and lower-power DC units, a single compact load that handles both saves a trip back to the van.

The TK4730 carries one standard AC and one DC charging socket and is rated at 5 kW AC and DC, with a 10 kW version available. It connects to the charger tester with a dedicated charging connector and runs on air cooling, with an emergency stop for safe operation. RS232 and CAN-BUS interfaces connect it to the test system, and universal casters make it easy to move between charging bays.

It works with field testers such as the Tunkia TD1320 and Tunkia TD1330. For higher power, see the Tunkia TK4710 DC load and the Tunkia TK4720 AC load.

AV-TEK helps you build the right load set for your test program. See all loads, EV charger testers and loads, and Tunkia instruments.
