REMOTE TERMINAL FOR AUTOMATIC / MANUAL OUTPUT ON-OFF CONTROL

The DC-DC Converter can be set to control the output Manually or Automatically.

Application of the Remote Control Terminal:

A. The converter can be set to manual control of the output via external switch

B. The remote On/Off function can be controlled via many types of On/Off switches and with various

DC sources between 8V-32V.

Once the Remote Terminal has been connected to a positive 8-32V, the converter will be modified to

Remote Control Mode and will remain in this mode until it is disabled either by reset

, or to

factory preset

. See section 11 and 12 for more detail information.
