Power Supply/Charger

Overview:

The PM224 supervised linear power supply/charger converts a low voltage “AC” input to a filtered and regulated
24VDC, 750mA continuous power limited output.

Specifications:

Input:

• 24VAC/40VA

Output:

• 24VDC output

• 750ma continuous supply current

• Filtered and electronically regulated output

• Thermal and short circuit protection with auto reset

Battery Backup:

• Built-in charger for sealed lead acid or gel type batteries

• Automatic switchover to stand-by battery when AC Fails

• PTC battery protection.

Supervision:

• AC fail supervision (form “C” contacts)

• Low battery supervision (form “C” contacts)

• Low battery disconnect prevents batteries from deep discharge

Additional Features:

• AC input and DC output LED indicators

• Includes battery leads
Board Dimensions (approximate): 5.25"L x 2.75"W x 1.5"H

Installation Instructions:

1. Connect proper transformer (24VAC, 40VA) to terminals marked [AC].

2. Measure output voltage before connecting devices. This helps avoid potential damage.

3. Connect devices to be powered to terminals marked [- DC +], carefully observing polarity.

4. When the use of stand-by batteries are desired, they must be lead acid or gel type.
Connect battery to terminals marked [- BAT +] on the unit (battery leads included).
Note: When batteries are not used a loss of AC will result in the loss of output voltage.

5. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory
relay output terminals marked [N.C., C, N.O. ].
Note: During normal operation (AC and battery connected). the N.C. and C relay contacts
will be in the closed position and the N.O. and C relay contacts will be in
the open position. These contacts are rated at 2 amps, 120VAC.
