Altronix LPS3WP12220 Manual

Altronix LPS3WP12220 outdoor linear power supply/charger is specifically designed to provide the power needed
by the most demanding security and access control applications. It converts a 220VAC 50/60Hz input into a
2.5A 12VDC continuous output. Unit's unique NEMA 4 UL Listed enclosure allows installation right at the outdoor
equipment it is designed to power.
Input:
• 220VAC 50/60Hz, 0.25A.
Output:
• 12VDC @ 2.5A continuous supply current.
• Filtered and electronically regulated output.
• Short circuit and thermal overload protection.
Battery Backup:
• Built-in charger for sealed lead acid or
gel type batteries.
LPS3WP12220 should be installed in accordance with The National Electrical Code and all applicable
Local Regulations.
1. Remove back plate inside enclosure by removing
the four (4) mounting screws (Fig. 2, pg. 2).
2. Mark and drill desired knockouts on the enclosure
to facilitate wiring (Fig. 1, pg. 2).
3. Secure back plate inside enclosure with the four (4)
mounting screws (Fig. 2, pg. 2).
4. Unit can be wall or pole mounted.
Wall Mount: Mark and drill holes to line up with
the top and bottom holes of
the enclosure flange.
Secure enclosure with appropriate
fasteners (Fig. 3 and Fig. 3a, pg. 3).
Pole Mount: Refer to the detailed pole mount
instructions (pg. 3).
Secure enclosure to earth ground.
5. Connect AC power to the black and white flying
leads of the transformer (Fig. 2, pg. 2).
Use 18 AWG or larger for all power connections
(Battery, DC output).
6. Measure output voltage at the terminals marked
[– DC +] before connecting devices.
This helps avoiding potential damage.
7. Connect devices to be powered to the terminals
marked [– DC +], carefully observing polarity
(Fig. 2, pg. 2).
Note: Power supplies mounted in weatherproof enclosures should be derated by approximately
50% to account for the extreme environmental conditions.
8. Connect optional stand-by battery to the terminals marked [– BAT +]. Battery leads included.
(A separate enclosure is needed for batteries). (Fig. 2, pg. 2).
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
