LV124 / LV148 ECU Outputs As Power Supply

ECUs as power supplies? It’s more common than you think.

Post number 4 in our series on #automotive #ECU #testing dives into questions we couldn’t ignore.
Modern ECUs are not just signal processors – they actively power sensors, actuators, and even other ECUs.
From HSDs and Half Bridges to smart fuses (E-Fuses) and terminal 30/31 outputs – these power outputs are everywhere.
But what are they called? How standardized are they? And how do they behave in 12V / 24V / 48V networks?

We took a deep, structured look – and yes, we can test them!
With our #RTStand #LV124 / #LV148, we perform:
• Short-circuit and interruption tests (e.g. VW 80000 E13/E17)
• Overcurrent tests
• Full LV124 / LV148 coverage
• Fully automated execution, logging and reporting

These are critical tests – and our customers can count on our system to handle them reliably, repeatably, and with full documentation.

We’re happy to exchange thoughts – and always ready for a deeper discussion.
