Altronix AL1024X220 Series Power Supply and Charger

Overview:
Altronix AL1024X220 is a power supply that converts a nominal 220VAC (working range 198VAC-256VAC) 50/60Hz input to a 24VDC regulating output (see specifications).

Installation Instructions:
Wiring methods should be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.

1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the enclosure. Drill the lower holes and install the fasteners. Place the enclosure’s upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 8). Secure enclosure to earth ground.

2. Connect AC circuit (220VAC, 50/60Hz) as follows: Green branch wire connects to earth (safety) ground lug . Line and Neutral to the connector on power supply board marked [L, N] respectively (Fig. 1, pg. 4). Use 14 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).

3. Measure output voltage before connecting devices. This helps avoiding potential damage.
   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.

4. Connect devices to be powered:

   • For Power Supply Board: connect to the terminals marked [+ DC –] (Fig. 1, pg. 4).
   • For Power Distribution Module(s): connect devices to be powered to the terminal pairs 1 to 4 marked [1P & 1N] through [4P & 4N] (Fig. 2, pg. 6) or 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3, pg. 6), carefully observing correct polarity.
     Note: When servicing the unit, AC mains should be removed.

5. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.

6. Connect appropriate signaling notification devices to terminals marked [AC FAIL] and [BAT FAIL] (Fig. 1, pg. 4) supervisory relay outputs.
   Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay must be used to provide a visual indication of AC power on.

7. Please ensure that the cover is secured with the provided key lock.

Wiring:
Use 14 AWG or larger for all power connections.
Note: Take care to keep power-limited circuits separate from non-power- limited wiring (220VAC, Battery).

Maintenance:

Unit should be tested at least once a year for the proper operation as follows:

Output Voltage Test: Under normal load conditions the DC output voltage should be checked for the proper voltage level.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the battery terminal and at the board terminals marked [– BAT +] to ensure that there is no break in the battery connection wires.

Note: Maximum charging current under discharges is 3.6A.
Note: Expected battery life is 5 years; however, it is recommended to change batteries in 4 years or less if needed.

CAUTION: De-energize unit prior to servicing.
For continued protection against risk of electric shock and fire hazard replace fuse with the same type and rating. Do not expose to rain or moisture .

CAUTION: Optional rechargeable stand-by batteries must match the
power supply output voltage setting. Keep power-limited wiring separate from non power-limited. Use minimum 0.25″ spacing.

Battery Size Calculation Worksheet:

• A. AL1024X220 series internal current consumption (stand-by) 0.05 A
• B. Load current consumption (stand-by) A
• C. Stand-by time required (hours) _ H
• D. Battery capacity required for stand-by (A+B)*C _AH
• E. AL1024X220 series internal power consumption (Alarm) _0.05 A
• F. Load current consumption (Alarm) _A
• G. Alarm duration (Hours; 15 Min. = 0.25 Hour) (Alarm) _ H
• H. Battery capacity required for Alarm (E+F)*G _AH
• I. Total calculated battery capacity D+H __AH
• J. Battery capacity required I*1.8 (safety factor) _AH

Note: AL1024X220 series power supply is designed to work with batteries up to 65AH.
Please note: line [I] must not exceeds 36AH. You have to reduce either stand- by current consumption or stand-by time in order to comply with requirements.
To determine actual battery size please round line [J] to the nearest larger standard battery size (e.g. 3.5 AH = 4.0 AH).
