Overview:
The OLS75/220 is a power limited supply/chargers that will convert a 220 VAC 50 / 60Hz input, into a 12VDC or
24VDC power limited output, with 2.5 amps of continuous supply current (see specifications).
Specifications:
•
Switch selectable 12VDC or 24VDC power limited output.
•
Input 220VAC 50 / 60Hz, .3 amp.
•
Maximum charge current .5 amp.
•
2.5 amps continuous supply current at 12VDC and 24VDC.
•
Filtered and electronically regulated outputs.
•
Built-in charger for sealed lead acid or gel type batteries.
•
Automatic switch over to stand-by battery when AC fails
(zero voltage drop).
•
AC input and DC output LED indicators.
•
AC fail supervision (form "C" contacts).
•
Low battery supervision (form "C" contacts).
• Short circuit and thermal overload protection.
•
Includes battery leads.
Specified at 25˚ C ambient.

Installation Instructions:
The OLS75/220 should be installed in accordance with The National Electrical Code
and all applicable Local Regulations.
1. Mount the OLS75/220 in desired location.
2. Set the OLS75/220 to desired DC output voltage via SW1 (see power supply voltage output selection chart).
3. Connect AC power to terminals marked [L & N], connect ground to terminal marked [G].
Use 18 AWG or larger for all power connections (Battery, DC output).
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 .25” spacing must be provided.
4. Connect devices to be powered to terminals marked [+ DC -- ].
Note: It is good operating practice to measure and verify output voltage before
connecting devices to ensure proper operation of equipment.
5. When the use of stand-by batteries are desired, they must be lead acid or gel type.
Connect battery to terminals marked [- BAT +] (battery leads included).
Use two (2) 12VDC batteries connected in series for 24VDC operation.
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 [N.C., C, N.O.].
