Installation Instructions
SMP10 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
- Mount SMP10 in the desired location/enclosure (mounting hardware included).
- Connect the proper transformer to the terminals marked [AC] (Voltage Output/Transformer Selection Table). Use 18 AWG or larger for all power connections (Battery, DC output).
- Set the SMP10 to the desired DC output voltage by setting the switch to the appropriate positions (Fig. 1a, pg. 2)(Voltage Output/Transformer Selection Table).
- Adjust output voltage by using the trim pot on the power supply board (Fig. 1a, pg. 2) prior to connecting devices. Keep power-limited wiring separate from non-power-limited wiring
- (115VAC, 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.
- Measure output voltage before connecting devices. This helps avoid potential damage.
- Connect devices to be powered to the terminals marked [– DC +] (Fig. 1, pg. 2).
- 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 +] (battery leads included).
- Use two (2) 12VDC batteries connected in series for 24VDC operation.
- When batteries are not used, a loss of AC will result in the loss of output voltage.
LED Diagnostics
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating condition. |
| ON | OFF | Loss of AC. The stand-by battery is supplying power. |
| OFF | ON | No DC output. Short circuit or thermal overload condition. |
| OFF | OFF | Loss of AC. Discharged or no stand-by battery. No DC output. |
Terminal Identification
| Terminal | Function/Description |

AC/AC
| Low voltage AC input (Voltage Output/Transformer Selection Table).
For 12VDC output use 28VAC or higher with a 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 the maximum input rating).
– DC +| 12VDC / 24VDC @ 10A continuous output.
– BAT +| Stand-by battery connections. Maximum charge rate 0.7A.
