Overview:

OLS75 power supply/charger converts 115VAC, 60Hz or 230VAC, 50Hz input, into a 12VDC or 24VDC @ 2.5 amps
of continuous supply current (see specifications). This general purpose power supply has a wide range of application for
access control and security system accessories that require additional power.

Installation Instructions:

The OLS75 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the OLS75 in the desired location/enclosure.
2. Slide [Power ON/OFF] switch to OFF position.
3. Set the OLS75 to the desired DC output voltage via SW1 (Voltage Output Selection Table).
4. Connect AC power to the terminals marked [L & N], connect ground to the terminal marked [G].

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).

5. Slide [Power ON/OFF] switch to ON position.
6. Measure output voltage before connecting devices. This helps avoiding potential damage.
7. Slide [Power ON/OFF] switch to OFF position.
8. Connect devices to be powered to the terminals marked [– DC +].
9. When the use of stand-by batteries is desired, they must be lead acid or gel type.

Connect battery to the terminals marked [-- BAT +] (battery leads included).

Use two (2) 12VDC batteries connected in series for 24VDC operation.

10. When batteries are not used, a loss of AC will result in the loss of output voltage.
11. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory

relay outputs marked [NC, C, NO].

12. Slide [Power ON/OFF] switch to ON position.
