Altronix SMP10PM Installation Instructions User Manual download pdf

Overview:

The SMP10PM is a supervised power supply that converts a low voltage AC input into 12VDC or 24VDC output with a

10 amp continuous supply current.

Specifications:

Voltage Output/Transformer Selection Table:

Output VDC Switch Position Transformer

12VDC @ 10 amp SW1 - Closed 24VAC or 28VAC / 175VA (Altronix model T2428175)

24VDC @ 6 amp SW1 - Open 24VAC or 28VAC / 175VA (Altronix model T2428175)

24VDC @ 10 amp SW1 - Open 24VAC or 28VAC / 300VA (Altronix model T2428300)

Installation Instructions:

The SMP10PM should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

1. Mount the SMP10PM in the desired location/enclosure.

2. Set the SMP10PM to the desired DC output voltage by setting the switches (Fig. 1a, pg. 2) to the

appropriate positions (Voltage Output/Transformer Selection Table).

3. 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.

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

5. Connect devices to be powered to the terminals marked [+ DC -].

6. When the use of stand-by batteries is desired, they must be lead acid or gel type. Connect 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.

7. Connect appropriate trouble reporting devices to AC Fail & 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 supplying power

OFF ON No DC output

OFF OFF Loss of AC. Discharged or no stand-by battery. No DC output
