Shutdown input

The shutdown input allows the output of the power supply to be switched off by means of a signal switch or external voltage.

• The shutdown takes place without delay, while switching on is delayed by up to 350 ms.
• When switched off, the output voltage is less than 2 V and the output power is less than 0.5 W.
• When units are connected in parallel, the voltage difference between the various negative output terminals must be less than 1 V.
• When operating several power supplies in series, only wiring option "A" with single signal switches is permitted.

Information regarding the use of the shutdown input Please note the following: Option C (see diagram below) requires current reduction capability of the voltage source. Do not use a blocking diode! The shutdown function does not include any safety functionality.
