Overview:

OLS20 power supply/charger converts 115VAC / 60Hz input, into a 12VDC @ 1 amp or 24VDC @ .5 amp of
continuous supply current (refer to specifications). This general purpose power supply has a wide range of application
for access control and security system accessories that require additional power.

Specifications:

Input:

• 115VAC / 60Hz, .5 amp.

Output:

• 12VDC or 24VDC selectable operation.

• .5 amp continuous supply current @ 24VDC
1 amp continuous supply current @ 12VDC.

• Filtered and electronically regulated outputs.

• Short circuit and thermal overload protection.

Battery Backup:

• Built-in charger for sealed lead acid or gel type batteries.
Maximum charge current .5 amp.

•

• Automatic switch over to stand-by battery when AC fails.

Additional Features:

• AC input and DC output LED indicators.

• Includes battery leads.

Board Dimensions (approximate): 2.6”W x 3.1”L x 1.3”H

Specified at 25˚ C ambient.

1. Mount the OLS20 in desired location/enclosure.

2. Set the OLS20 to desired DC output voltage via SW1

(refer to Voltage Output Selection Table).

3. Connect AC power to connector #1

(Fig. 1) (black & white flying leads) and ground (green flying lead)

Use 18 AWG or larger for all power connections(Battery, AC input).

Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
