Remote control of output voltage

The shut-down input can also be used to remotely adjust the output voltage between typically 14Vdc and 28Vdc.

Please be aware, that a continuously change of the output voltage of more than 4V reduces the lifetime. We recommend not adjusting the output voltage more than 50 times per day when the adjustment is larger than 4V.

Remote control of output voltage 1:
Remote control of the output voltage; Applying the control voltage

Instructions:

  1. Set the unit into “Single Use” mode.
  2. Set the output voltage adjustment (24-28V) to the maximum desired voltage.
  3. Apply a control voltage between typ. 5V DC and typ. 12V DC to pin 15 and main ground (negative output voltage). The control voltage must be permanently supplied.
