Installation Instructions:
OLS350220 should be installed in accordance with The National Electrical Code and all applicable
Local Regulations.
1. Mount the OLS350220 in the desired location/enclosure (mounting hardware included).
2. 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.
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. 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.
5. 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.
6. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory
relay outputs marked [NC, C, NO].

Off-Line Power Supply/Charger
Installation Guide
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.
