Altronix SMP10PM Supervised Power Supply Charger
Overview
Altronix SMP10PM is a supervised power supply that converts a low voltage AC input into 12VDC or 24VDC output with a 10A continuous supply current.
Specifications
Input:
- Input 24/28VAC. (Voltage Output/Transformer Selection Table).
Output:
- 12VDC or 24VDC selectable output.
- 10A supply current.*
- Filtered and electronically regulated outputs.
- Short circuit and thermal overload protection.
Battery Backup:
- Built-in charger for sealed lead acid or gel-type batteries.
- Maximum charge current 0.7A.
- Zero voltage drop when switching over to battery backup.
Supervision:
- AC fail supervision (form “C” contacts).
- Battery presence and low battery supervision (form “C” contacts).
Indicators:
- AC input and DC output LED indicators.
- Board Dimensions (W x L x H approximate): 7” x 4.25” x 1.25” (177.8mm x 107.9mm x 31.8mm). * Specified at 25˚C ambient.
Voltage Output/Transformer Selection Table
| Output VDC | Switch Position | Transformer |
|---|---|---|
| 12VDC @ 10A | SW1 – ON | 24VAC or 28VAC / 175VA (Altronix model T2428175) |
| 24VDC @ 6A | SW1 – OFF | 24VAC or 28VAC / 175VA (Altronix model T2428175) |
| 24VDC @ 10A | SW1 – OFF | 24VAC or 28VAC / 300VA (Altronix model T2428300) |
Installation Instructions
SMP10PM should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
-
Mount the SMP10PM in the desired location/enclosure (mounting hardware included).
-
Set the SMP10PM to the desired DC output voltage by setting the switch (Fig. 1a, pg. 2) to the appropriate position (Voltage Output/Transformer Selection Table). Adjust output voltage by using the trimpot on the power supply board (Fig. 1a, pg. 2) prior to connecting devices.
-
Connect 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.
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. -
Measure output voltage before connecting devices. This helps avoid potential damage.
-
Connect devices to be powered to the terminals marked [– DC +].
-
When the use of stand-by batteries is desired, they must be lead acid or gel type. Connect the battery to the 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. -
Connect appropriate trouble reporting devices to AC Fail and Low battery supervisory relay outputs marked [NC, C, NO]. Use 22 AWG to 18 AWG for AC Fail / Low Battery reporting. AC Failure will report in 5 minutes. For a 6-hour delay on reporting cut resistor R1.
LED Diagnostics
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating condition. |
| ON | OFF | Loss of AC. Stand-by battery is supplying power. |
| OFF | ON | No DC output. |
| OFF | OFF | Loss of AC. Discharged or no stand-by battery. No DC output. |
Terminal Identification

AC/AC
| Low voltage AC input (Voltage Output/Transformer Selection Table).
For 12VDC output use 28VAC or higher with 175VA power rating or higher. For 24VDC output use 28VAC with 175VA power rating or higher.
Caution: Do not apply voltages above 28VAC (28VAC is maximum input rating).
– DC +| 12VDC / 24VDC @ 10A continuous output.
AC FAIL NC, C, NO| Indicate loss of AC power, (e.g. connect to audible device
or alarm panel). AC report delay is approx. 1 min. Relay normally energized
when AC power is present.
Contact rating 1A @ 120VAC / 28VDC.
Low Battery NC, C, NO
| Indicate low battery or battery presence condition, (e.g. connect to audible device or alarm panel). Battery presence delay is approx. 3 mins. Circuit will restore 5 secs. after battery is detected. Relay normally energized during proper battery operation. Contact rating 1A @ 120VAC / 28VDC.
Low battery threshold: 12VDC output threshold set @ approximately 10.5VDC, 24VDC output threshold set @ approximately 21VDC. Battery Presence: 12 or 24VDC battery presence threshold is approximately 4VDC. Battery presence is automatically tested about every 5 mins. If battery is determined absent, the unit will automatically test for presence about every 5 secs.
– BAT +| Stand-by battery connections. Maximum charge rate 0.7A.
