Altronix OLS120D2X dual output power supply/charger converts a 115VAC, 50/60Hz or 230VAC, 50/60Hz
input to a 12VDC/24VDC output and a 12VDC fixed output (see specifications). This unit has a wide range of
applications for access control and security system accessories that require additional power.
Input:
• Universal input 115VAC, 50/60Hz, 0.95A or
230VAC, 50/60Hz, 0.6A.
• Input fuse rated @ 5A/250V.
Output:
• DC1: 12VDC or 24VDC @ 3A.
DC2: 12VDC @ 1A.
Note: If DC2 is not used, DC1 rating is
12VDC or 24VDC rated @ 4A max.
• Filtered and electronically regulated output.
• Short circuit and thermal overload protection.
Battery Backup:
• Built-in charger for sealed lead acid or
gel type batteries.
Wiring methods should be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI and with
all local codes and authorities having jurisdiction. Product is intended for indoor use only.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure's upper keyholes over the two upper screws; level and secure. Mark the position of the lower
two holes. Remove the enclosure. Drill the lower holes and install three fasteners. Place the enclosure's

upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all
screws (Enclosure Dimensions, pg. 4). Secure enclosure to earth ground.
2. Slide [Power ON/OFF] switch t o the OFF position (Fig. 1, pg. 3).
3. Set the DC1 output voltage via DIP switch: OFF for 24VDC operation or ON for 12VDC operation
(Fig. 1, pg. 3). DC2 output voltage is fixed at 12VDC operation.
Keep power-limited wiring separate from non power-limited wiring (115VAC/230VAC, 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

8. Connect 12VDC or 24VDC (depending on DIP switch setting) device to be powered to the terminals
marked [– DC1 +]. Connect 12VDC device to be powered to the terminals marked [– DC2 +] (Fig. 1, pg. 3).
9. When use of stand-by batteries is desired, they must be lead acid or gel type.
Circuit
Connect battery/batteries to the terminals marked [– BAT + ] (Fig. 1, pg. 2).
12VDC operation only: Use one (1) 12VDC battery for 12VDC backup.
24VDC and 12VDC simultaneous operation: Use two (2) 12VDC batteries connected in series for
24VDC backup.
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 the ON position (Fig. 1, pg. 3).
