Psu compatible load adaption

A load module for connecting to a power supply having a maximum power capability, the load module comprising:

• a load;
• an input for receiving an input voltage from the power supply
• a power regulator adapted to receive the input voltage and adapted to provide a regulated power to the load;
• a current sensor for sensing a current provided by the power supply;
• a voltage sensor for sensing the input voltage;
• and
• a controller for controlling the power regulator,
• wherein the controller is arranged to operate in a configuration mode, wherein the controller is arranged to control the power regulator to draw a current from the input that gradually increases until the input voltage drops, wherein the current at which the input voltage drop is indicative of a the maximum power capability of the power supply, wherein the controller is arranged to determine the maximum power capability of the power supply based on the sensed current and the sensed input voltage close to the event that the input voltage drops,
• wherein the power regulator comprises a current drawing circuit adapted to draw the current from the input that gradually increases until the input voltage drops, such that no current flows through the load during the configuration mode.
