Altronix OLS350 Off-Line Power Supply-Charger Installation Guide

OLS350
Off-Line Power Supply/Charger
Installation Guide

Overview:

Altronix OLS350 power supply/charger converts 115VAC, 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:

• 115VAC, 60Hz, 5A.

Output:

• 24VDC output.
• 12A continuous supply current.
• Filtered and electronically regulated output.
• Short circuit and thermal overload protection.

Supervision:

• AC fails 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.
• Battery leads included.
  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:

OLS350 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

1. Mount the OLS350 in the desired location/enclosure (mounting hardware included).

2. Connect AC power to the terminals marked [L & N], and 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 (115VAC, 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 avoid 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 the 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].

LED Diagnostics:

Terminal Identification:

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.
The relay is normally energized when AC power is present. Contact rating 1A 0 28VDC.
Low Battery
NC, C, NO| Used to indicate low battery condition, e.g. connect to the alarm panel.
The relay is normally energized when DC power is present. Contact rating 1A 0 28VDC
Low battery threshold: 24VDC output threshold set 0 approximately 21 VDC.
— BAT +| Stand-by battery connections. Maximum charge rate 0.7A.
