Altronix LPS3C12X220 Linear Power Supply-Charger Installation Guide
Overview:
Altronix LPS3C12X220 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 to a 2.5A, 12VDC output.
Fig. 1
Specifications:
Input:
- 220VAC 50/60Hz rated @ 0.25A.
Output:
- 12VDC output.
- 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.
- Maximum charge current 500mA.
- Automatic switch over to stand-by battery when AC fails (zero voltage drop).
- Fused battery protection (circuit breaker available).
Visual Indicators:
- AC/DC power LED indicator.
Features:
- Includes battery leads.
- Enclosure:
– Combination knockouts are 1/2” and 3/4”.
– Accommodates one (1) 12VDC/12AH battery.
Enclosure Dimensions (H x W x D):
15.5” x 12” x 4.5” (393.7mm x 304.8mm x 114.3mm)
Installation Instructions:
LPS3C12X220 should be installed in accordance with the National Electrical Code and all applicable Local Regulations.
-
Mount the LPS3C12X220 in the desired location.
-
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 voltage before connecting devices. This helps avoiding potential damage.
Keep power-limited wiring separate from non power-limited wiring (220VAC 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 qualified service personnel. -
Connect devices to be powered to the terminals marked [- DC +] (Fig. 1).
-
Connect battery to the terminals marked [- BAT +] (Fig. 1) on the unit (battery leads included).
Note: When batteries are not used, a loss of AC will result in the loss of output voltage.
Maintenance:
Unit should be tested at least once a year for the proper operation as
follows:
Output Voltage Test: Under normal load conditions the DC output voltage
should be checked for proper voltage level.
Battery Test: Under normal load conditions check that the battery is
fully charged, check specified voltage both at the battery terminal and at the
board terminals marked [- BAT +] to ensure that 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.
