Altronix LPS3C24X220 Linear Power Supply-Charger
Overview
LPS3C24X220 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 60Hz input to a 2.5A 24VDC continuous power-limited output.
Specifications
Input:
- 220VAC 50/60Hz 0.5A.
Output:
- 24VDC 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).
- Battery leads included.
Visual Indicators:
- AC/DC power LED indicator.
Enclosure:
- Enclosure:dimensions (H x W x D approximate): 15.5″ x 12″ x 4.5″ (393.7mm x 304.8mm x 114.3mm).
- Combination knockouts are 1/2″ and 3/4″.
- Accommodates up to two (2) 12VDC/12AH batteries.

Installation Instructions
LPS3C24X220 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
-
Mount LPS3C24X220 in the desired location.
-
Connect AC power to the black and red 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) as marked on the
unit (battery leads included).
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 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 (see power supply voltage output
specifications chart).
Battery Test: Under normal load conditions, check that the battery is
fully charged, check specified voltage both at 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.
Terminal Identification
| Terminal Legend | Function/Description |
|---|---|
| AC/AC | Low voltage AC input (28VAC 100VA). |
| – BAT + | Stand-by battery connections. |
| – DC + | 24VDC @ 2.5A continuous output. |
LED Diagnostics
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating condition. |
| ON | OFF | Loss of AC. Stand-by battery is supplying power. |
| OFF | ON | No DC output. |
| OFF | OFF | Loss of AC. Discharged or missing stand-by battery. No DC output. |
Enclosure Dimensions (H x W x D approximate)
15.5” x 12” x 4.5” (393.7mm x 304.8mm x 114.3mm)
