OLS180220 Off-Line Power Supply
Installation Guide

Overview

Altronix OLS180220 power supply/charger converts 220VAC (working range 198VAC- 256VAC), 50/60Hz input into a 12VDC or 24VDC at 6A of continuous supply current  (see specifications). This general-purpose power supply has a wide range of applications for access control and security system accessories that require additional power.

Installation Instructions:

OLS180220 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

1. Mount the OLS180220 in the desired location/enclosure (mounting hardware included).

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

3. Set the OLS180220 to the desired DC output voltage via SW1 (Voltage Output Selection Table).
   Keep power-limited wiring separate from non-power-limited wiring (220VAC 50/60Hz Input, Battery Wires). Minimum 0.25” spacing must be provided.
   CAUTION: Do not touch exposed metal parts.
   Shut branch circuit power before installing or servicing equipment.
   There are no user-serviceable parts inside.
   Refer installation and servicing to qualified service personnel.

4. Connect AC power to the terminals marked [L & N], and 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. Measure output voltage before connecting devices. This helps avoid potential damage.

6. Connect devices to be powered to the terminals marked [– DC +].

7. When the use of stand-by batteries is desired, they must be lead acid or gel type.
   Connect the battery to the terminals marked [– BAT +] (battery leads included).
   Use two (2) 12VDC batteries connected in series for 24VDC operation.
   Note: When batteries are not used, a loss of AC will result in the loss of output voltage.

8. Connect appropriate signaling notification devices to AC Fail and Low Battery supervisory relay outputs marked [NC, C, NO].

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

Terminal Identification

ground.
— DC +| 12VDC / 24VDC @ 6A continuous supply current.
AC FAIL
NC, C, NO| Used to notify loss of AC power, e.g. connect to audible device or alarm panel.
Relay is normally energized when AC power is present. Contact rating 1A @ 28VDC
Low Battery
NC, C, NO| Used to indicate low battery condition, e.g. connect to the alarm panel.
Relay is normally energized when DC power is present. Contact rating 1A @ 28VDC.
Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC.
24VDC output threshold set @ approximately 21 VDC.
— BAT +| Stand-by battery connections. Maximum charge rate 0.7A.
