SMP3PM - Supervised Power Supply/Charger
Overview:
SMP3PM is a supervised power supply/charger that converts a low voltage AC input, into a 12VDC or 24VDC
selectable output, with 2.5 amp of continuous supply current (see specifications).
Specifications:
Voltage Output/Transformer Selection Table:
Output VDC Switch Position Max. Load DC Transformer Requirements
12VDC
SW1 Closed 2.5 amp 16VAC/40VA (TP1640), 24VAC or 28VAC/100VA (T2428100)
24VDC SW1 Open 2.5 amp 24VAC or 28VAC/100VA (T2428100)
Note: Transformers with higher VA ratings may be used for all output voltages above as long as you
do not exceed 28VAC or 45VDC.
Installation Instructions:
The SMP3PM should be installed in accordance with The National Electrical Code
and all applicable Local Regulations.
1. Mount the SMP3PM board in desired location/enclosure.
2. Set the SMP3PM to desired DC output voltage via SW1 (Voltage Output/Transformer Selection Table).
3. Connect proper transformer to terminals marked [AC] (Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting).
4. Measure output voltage before connecting devices. This helps avoid potential damage.
5. Connect devices to be powered to terminals marked [ + DC -- ].
6. 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 board (battery leads included).
Use two (2) 12VDC batteries connected in series for 24VDC operation.
Note: When batteries are not used a loss of AC will result in the loss of output voltage.
7. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory
relay outputs marked [NC, C, NO].
