Electronic load module and a method and a system therefor

A method for operating an electronic load module, wherein the electronic load module comprises:

• a digital control circuit configured to be connected to a power controller via a data bus connector;
• an active load operatively connected to and controlled by said digital control circuit;
• and
• a first input operatively connected to the active load and configured to be connected to a device under test;
• wherein the method comprises:
• receiving control data from said connectable power controller via the data bus connector;
• controlling the active load based on the received control data using the digital control circuit and the connectable power controller to generate and maintain an ambient temperature of the device under test and to sink a defined current from said connectable device under test via the first input.

An electronic load module comprising:

• a digital control circuit configured to be connected to a power controller via a data bus connector;
• an active load operatively connected to and controlled by said digital control circuit;
• and
• a first input operatively connected to the active load and configured to be connected to a device under test,
• wherein the digital control circuit is configured to receive control data from said connectable power controller via the data bus connector and to control the active load, based on the received control data, to sink a defined current from said device under test via the first input, wherein the active load is configured to be controlled by said digital control circuit, based on the received control data, to generate and maintain an ambient temperature of the connectable device under test.

A system for electrical loading of a device under test, wherein the system comprises:

• a power controller configured to control at least one power converter circuit within the device under test;
• a physical housing of the device under test;
• a temperature sensor operatively connected to said power controller and being configured to measure an ambient temperature inside said physical housing;
• an electronic load module configured to be controlled by said power controller and being configured to be arranged within the device under test, wherein the electronic load module comprises an active load and a digital control circuit configured to receive control data from the power controller and to control the active load, based on the received control data, to sink a defined current from said device under test,
• and wherein the electronic load module is configured to generate and maintain a defined ambient temperature within the physical housing of the device under test using the active load, which is controlled by the digital control circuit based on the received control data, and
• the power controller is configured to control the ambient temperature within the physical housing based on said measured ambient temperature and by the electronic load module.
