Altronix SMP5 User manual

Overview:
SMP5 power supply/charger converts low voltage AC input into 6VDC, 12VDC or 24VDC @ 4A of continuous
supply current (see specifications). This general purpose power supply has a wide range of applications for access
control, security and CCTV system accessories that require additional power.
Specifications:
* Specified at 25˚C ambient.

6VDC ON OFF 16VAC / 40VA (TP1640)
12VDC OFF OFF 24VAC or 28VAC / 100VA (T2428100), or 16VAC / 100 VA (T16100)
24VDC OFF 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 28VAC or 45VDC.
Installation Instructions:
SMP5 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount SMP5 board in the desired location/enclosure.
2. Set DC output voltage with switches (Voltage Output/Transformer Selection Table).
3. Connect a proper transformer to the terminals marked [AC] (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 avoiding potential damage.
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.
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 --- ] (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.
