SMP5: Power Supply/Charger

SMP5 power supply/charger converts low voltage AC input into 6VDC, 12VDC or 24VDC @ 4 amp 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.

Input:

16VAC to 28VAC 

Output:

  • 6VDC, 12VDC or 24VDC selectable output.
  • 4 amp supply current.
  • Filtered and electronically regulated outputs.
  • Short circuit and thermal overload protection.

Battery Backup:

  • Built-in charger for sealed lead acid or gel type batteries.
  • Maximum charge current 0.3 amp.
  • Zero voltage drop when switching over to battery backup.
  • Specified at 25˚ C ambient.

Visual Indicators:

AC input and DC output LED indicators.

Features:

  • Extremely compact design.
  • Includes battery leads.
  • Snap Trac compatible

Board Dimensions (W x L x H approx.):

3” x 3.5” x 2” (76.2mm x 88.9mm x 50.8mm)

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:

The SMP5 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

1. Mount the SMP5 board in the desired location/enclosure.

2. Set DC output voltage with switches

3. Connect a proper transformer to the terminals marked [AC]. 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.
