Description and Operation

Edwards DC power supplies are easy to install, convection

cooled low voltage power sources designed to operate

DC powered products including bells, buzzers, horns and

beacons.

Installation

1. Mount the power supply using one of the following

methods.

a. Mount using (2) M3 threaded holes located on

either the side or the bottom of the power supply.

b. Mount the power supply using the (2) predrilled

3.5 mm holes located on either the side or the

bottom of the power supply.

NOTE: Pre-drilled holes on Cat. Nos. S-40-24 and S-60-24

are accessible without removal of cover.

For Cat. No. S-25-24 only, remove the single screw

(located in the corner of the power supply) securing

the cover on the power supply. Slide the cover

back and then lift up and remove the cover.

Replace the cover on the Cat. No. S-25-4 power

supply and secure using screw removed in step

WARNING

Prior to making connections, ensure the supply voltage is

turned off to prevent accidental electric shock.

2. Connect supply wiring to terminal block TB1 (Figure

1, 2 or 3) as follows. Using a three-wire cord, connect

the black conductor (Line) to the terminal labeled "L",

connect the white conductor (Neutral) to the terminal

labeled "N" and connect the green conductor (Ground)

to the terminal labeled .

3. Connect a wire from the positive side of the load to

the terminal screw labeled "V+". Connect a wire from

the negative side of the load to the terminal screw

labeled "V-".

4. After all electrical connections have been made, turn

on the supply voltage. The green power LED should

illuminate indicating voltage output.

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.
