Altronix AL624ET Installation Instructions

The AL624ET Linear Power Supply / Charger converts a 115VAC 60Hz input to a low voltage DC output.
This general purpose power supply has a wide range of applications for access control, security and CCTV system
accessories that require additional power.
Agency Listing:
• CE European Conformity.
Input:
• 115VAC, 60 Hz 1.2A.
Output:
• 12VDC @ 1.2A 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.
• Automatic switch over to stand-by battery when AC fails.
• Maximum charge current 0.3A.
• PTC battery protection.
Output
12VDC @ 1.2A
continuous supply current
1. Mount AL624 board in the enclosure (see reverse).
2. Unit is factory set for 12VDC.
3. Connect a proper transformer to the terminals marked [AC] (refer to voltage output/transformer selection table).
Use 18 AWG or larger for all power connections (Battery, DC output).
Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25" spacing must be provided.
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
5. Devices to be powered should be connected to the terminals marked [+ DC] and [DC – BAT], carefully observing polarity.
6. Connect battery to the terminals marked [BAT +] and [DC – NEG] (battery leads included)
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
