SMP5E
Power Supply/Charger Kit
Overview:
SMP5E High Current Power Supply/Charger converts a low voltage AC input to a low voltage DC output. This general
purpose power supply has a wide range of applications for access control, security, and CCTV system accessories that
require additional power.

provided the input voltage does not exceed 28VAC or 45VDC.
Installation Instructions:
The SMP5E should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the SMP5 board in enclosure (as shown on reverse).
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).
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 avoid potential damage.
5. Connect devices to be powered to terminals marked [+ DC –].
6. When the use of stand-by batteries are desired, they must be lead acid or gel type.
Connect battery to 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.
