Altronix OLS350220 Off-Line Power Supply Charger
Overview:
Altronix OLS350220 power supply/charger converts 220VAC (working range 198VAC – 256VAC), 50/60Hz input into 24VDC at 12A of continuous supply current (see specifications). This general purpose power supply has a wide range of applications for access control and security system accessories that require additional power.
Specifications:
Input
- 220VAC (working range 198VAC – 256VAC), 50/60Hz, 2.5A.
Output
- 24VDC output.
- 12A continuous supply current.
- Filtered and electronically regulated output.
- Short circuit and thermal overload protection.
Supervision:
- AC fail supervision (form “C” contacts).
- Low battery supervision (form “C” contacts).
Visual Indicators:
- AC input and DC output LED indicators.
Battery Backup:
- Built-in charger for sealed lead acid or gel type batteries.
- Automatic switch over to stand-by battery when AC fails.
- Maximum charge current 0.7A.
Features:
- Includes battery leads.
Board Dimensions (L x W x H approx.):
- 7.5” x 4.5” x 1.75” (190.5mm x 114.3mm x 44.5mm).
Installation Instructions:
OLS350220 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
-
Mount the OLS350220 in the desired location/enclosure (mounting hardware included).
-
Connect AC power to the terminals marked [L & N], connect ground to the terminal marked [G]. Use 18 AWG or larger for all power connections (Battery, DC output, AC input). Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting). 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. -
Measure output voltage before connecting devices. This helps avoiding potential damage.
-
Connect devices to be powered to the terminals marked [– DC +]. When the use of stand-by batteries is desired, they must be lead acid or gel type.
-
Connect battery to the terminals marked [– BAT +] (battery leads included).
Note: When batteries are not used, a loss of AC will result in the loss of output voltage. -
Connect appropriate signaling notification devices to AC Fail & Low battery supervisory relay outputs marked [NC, C, NO].
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. Short circuit or thermal overload condition. |
| OFF | OFF | No DC output. Loss of AC. Discharged or no battery present. |
Terminal Identification:
| Terminal Legend | Function/Description |
|---|---|
| L, G, N | Connect 220VAC to these terminals: L to Hot, N to Neutral, G to |
ground.
– DC +| 24VDC @ 12A continuous supply current.
AC FAIL
NC, C, NO
| Used to notify loss of AC power, e.g. connect to audible device or alarm
panel. Relay normally energized when AC power is present. Contact rating 1A @
28VDC.
Low Battery NC, C, NO| Used to indicate low battery condition, e.g. connect to
alarm panel.
Relay normally energized when DC power is present. Contact rating 1A @ 28VDC Low battery threshold: 24VDC output threshold set @ approximately 21VDC.
– BAT +| Stand-by battery connections. Maximum charge rate 0.7A.
