12/24 V DC Power Supply Unit.
The Power Supply Unit WGDC-2S can be set to the output voltage of 12 volt, 24 volt, or to softstart. The softstart functionality makes the power supply unit particularly suitable for precise regulation of the slat angle of blinds because the switch in the output voltage of 12 volt to 24 volt occurs only after one second of operation.
The integrated changeover relay bridges contacts internal, if there’s no control voltage applied. As a result, the connected drive outputs are fixed in their position.
