Switching outputs of multiple DC power supplies R&S®NGL200 / R&S®NGM200

All channels of DC power supplies R&S®NGL200 and R&S®NGM200 are isolated against the grounding equipment conductor and against the digital ground of the instrument. Therefore, channels can be connected in parallel for increasing the current capability, or in series for achieving higher voltages or dual-voltage supplies. In the case of parallel and serial connections it is usually desired to switch all channels simultaneously on and off for protecting the supplied circuitry and for avoiding overcurrent on other power supply channels.

This application note describes how to connect and configure DC power supplies R&S®NGL200 and R&S®NGM200 for synchronized on and off switching of all channels across multiple power supplies.
