Installation Instructions

Overview:
LPS3WP12 weatherproof linear power supply/charger is specifically designed to provide the power needed by the most
demanding security and access control applications. It will convert a 115VAC 60Hz input to a 2.5 amps 12VDC continu-
ous power limited output. Unit‘s unique NEMA 4 UL Listed enclosure allows installation right at the outdoor equipment
it is designed to power.
Specifications:
• Input 115 VAC 60Hz, .5 amp.
• 12VDC power limited output.
• Maximum charge current .5 amp.
• 2.5 amp continuous supply current.
• Filtered and electronically regulated output.
• Built-in charger for sealed lead acid or gel type batteries.
• Automatic switchover to stand-by battery when AC Fails.
• Thermal and short circuit protection with auto reset.
• Fused battery protection (circuit breakers available).
• AC input and DC output LED indicators.

Installation Instructions:
The LPS3WP12 should be installed in accordance with The
National Electrical Code and all applicable Local Regulations.
1.
Mount the LPS3WP12 in desired location.
2. Connect AC power to the black and white flying leads of
the transformer (Fig. 1). Use 18
AWG or larger for all power
connections (Battery, DC output).
3. Connect devices to be powered to terminals marked
[- DC +] (Fig. 1).
4. Measure output voltage before connecting devices. This helps av
oid potential damage.
5. Connect battery to terminals marked [- BAT +] (Fig. 1) on the power supply board (battery leads included).
Note:
When batteries are not used a loss of AC will result in loss of output voltage.
