Abstract

A power supply circuit for laser apparatus is disclosed, comprising an input for a mains supply, an output, respective positive and negative paths from the input to the output and switch means provided in both negative and positive paths. A differential current sensor may be provided to detect current imbalance due to faults such as faults to earth (ground) at the output.
