These units will convert a 115VAC / 60Hz input, into a regulated 12VDC or 24VDC output up 2.5 amp of
continuous load current (see specifications).
• Maximum charge current .5 amp.
• Filtered and electronically regulated outputs.
• Built-in charger for sealed lead acid or gel type batteries.
• Automatic switch over to stand-by battery when
AC fails (zero voltage drop).
• AC input and DC output LED indicators.

Power Supply Voltage Output Specifications: *

Output VDC
12VDC SW1 - Closed (Fig. 1B, pg. 3)
24VDC SW1 - Open (Fig. 1B, pg. 3)
*Specified at 25˚ C ambient.

Installation Instructions:

The unit should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the unit in desired location.
2. Set SW1 on the power supply board to the desired DC output voltage
(power supply voltage output specification chart).
3. Connect AC power to terminals marked [L & N], connect ground to terminal marked [G] (if used).
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting).
Keep power limited wiring low battery, AC fail separate from non-power limited wiring
(115VAC / 60Hz Input, Battery Wires, DC Output). Minimum .25" spacing must be provided.
