A power supply () for providing a desired current to an electric load () broadly comprises: a current limiter () for providing a desired current; a current sensor () for determining the actual current supplied by the current limiter and providing a feedback signal () to the current limiter for causing the current limiter to reduce the error between the desired and the actual currents; and a test circuit () for temporarily changing the actual current sensed by the current sensor to a level different from the desired current for causing the current limiter to adjust the magnitude of the current provided thereby; whereby the operation of the power supply may be tested. The invention also provides an improved method of operating such a power supply.
