Altronix OLS120D2X Installation Manual

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.
• Maximum charge current 0.7A.
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.

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
