## D575.00520 (Hartmann)
|
|
|
|
|
|
|
|
The test was performed with [DI/OT Loopback Peripheral Boards](https://ohwr.org/project/diot-pb-lbk/-/wikis) with load resistors soldered for 30W load on the 12V rail per Peripheral Board. Current readout from both PSUs was taken from their PMBus interface using the _diot\_util_ software running on the [DI/OT System Board v2](https://ohwr.org/project/diot-sb-zu/-/wikis).
|
|
|
|
|
|
|
|
Result: D575.00520 shares correctly the load between two PSUs in the DI/OT crate with a difference of ~1A, independently from the load.
