Edwards S Series DC Power Supplies are easy to install, convection cooled low voltage power sources designed to oeprate DC powered products including bells, buzzers, horns and beacons.

Power supplies can be easily mounted using one of two methods. For the Cat. No. S-25-24, remove the single screw securing the cover to the power supply. Slide the cover off and then lift up and remove the cover. Mount the power supply using the two predrilled 3.5 mm holes located on either the side or the bottom of the power supply. Replace the cover and secure using the previously removed screws.

For Cat. No's. S-40-24 and S-60-24, simply mount using the threaded holes on the side or bottom. Holes are accessible without the removal of the cover.

The output is factory set for 24V DC and no adjustment should be required. However, if voltage adjustment is necessary, turn the voltage adjustment potentiometer "SVR1" counterclockwise to lower the voltage or clockwise to increase the voltage. The voltage is adjustable from 21.6V to 26.4V.
