Altronix AL624E Service manual

Overview:
Altronix AL624E Linear Power Supply/Charger converts a low voltage AC 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.
Specifications:
Voltage Output/Transformer Selection Table:
Output
(continuous supply current) Voltage Selector (JMPR) Transformer
6VDC @1.2A Cut Jumper J2 Only 12VAC / 20 VA (Altronix model TP1220)
12VDC @ 1.2A Leave J1 & J2 Intact 16.5VAC / 20 VA (Altronix model TP1620)
24VDC @ 750mA Cut Jumper J1 Only 24VAC / 40 VA (Altronix model TP2440)
Installation Instructions:
1. Mount AL624 into enclosure (Fig. 1, pg. 2).
2. Mount AL624E in desired location.
3. Unit is factory set for 12VDC. For 6VDC output cut jumper J2, for 24VDC output cut Jumper J1.
4. Connect proper transformer to terminals marked [AC] (Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery, DC output).
5. Measure output voltage before connecting devices. This helps avoiding potential damage.
6. Connect devices to be powered to the terminals marked [+ DC] and [DC –BAT] carefully observing polarity.
7. 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.
LED Diagnostics:
Red (DC) Green (AC) Power Supply Status
ON ON Normal operating conditions
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.
