Output Voltage Switch Position Transformer Requirements
SW1 SW2 (Recommended Altronix Part #’s)
6VDC Closed/On Open/Off 16VAC / 40VA (TP1640)
12VDC Open/Off Open/Off 28VAC or 28VAC / 100VA (T2428100), or 16VAC / 100 VA (T16100)
24VDC Open/Off Closed/On 28VAC / 175VA (T2428175)
Note: Transformers with higher power (VA) ratings may be used for all output voltages selected above
provided the input voltage does not exceed 28V
AC or 45VDC.
Installation Instructions:
The SMP5 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the SMP5 in desired location / enclosure.
2. Set DC output voltage with switches (refer to Voltage Output/Transformer Selection Table).
3. Connect proper transformer to terminals marked [AC] (see Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery, DC output).
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-bybatteries are desired,theymust be lead acid or gel type.
Connect batteryto terminals marked [+ BAT---] (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.
