Linear Power Supply/Charger

Overview:

LPS3C12X 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 50/60Hz input to a 2.5 amp, 12VDC output.

Specifications:

Input:

• Input 115VAC 50/60Hz, .5 amp.

Output:

• 12VDC output.

• 2.5 amp continuous supply current.

• Filtered and electronically regulated output.

• Thermal and short circuit protection with auto reset.

Battery Backup:

• Automatic switch over to stand-by battery when AC Fails.

• Built-in charger for sealed lead acid or gel type batteries.

• Maximum charge current .5 amp.

• Fused battery protection (circuit breakers available).

• Includes battery leads.

Visual Indicators:

• AC input and DC output LED indicators.

Installation Instructions:

The LPS3C12X should be installed in accordance with The National Electrical Code and all applicable
Local Regulations.

1. Mount the LPS3C12X 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).
Measure output v

3.

4. Connect devices to be powered to terminals marked [- DC +]

5. Connect battery to terminals marked [- BAT +]
Note: When batteries are not used a loss of AC will result in loss of output voltage.

Maintenance:

Unit should be tested at least once a y
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level

(Power Supply Voltage Output Specifications Chart).

y Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at

Batter
battery terminal and at the board terminals marked [- BAT +] to insure there is no break in the battery connection wires.

Note: Maximum charging current under discharge is 500mA.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
