SMP3 power supply/charger converts low voltage AC input into 6VDC, 12VDC or 24VDC @ 2.5 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.
Installation Instructions:
The SMP3 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
- Mount the SMP3 in the desired location / enclosure.
- Set DC output voltage with switches (refer to Voltage Output/Transformer Selection Table).
- 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).
- Measure output voltage before connecting devices. This helps avoiding potential damage.
- Connect devices to be powered to the terminals marked [ + DC – ].
- 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.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
Input:
- 16VAC to 28VAC (see transformer selection table).
Output:
- 6VDC, 12VDC or 24VDC selectable output.
- Thermal overload and short circuit protection.
- 2.5 amp continuous supply current*.
- Filtered and electronically regulated output.
Battery Backup:
- Built-in charger for sealed lead acid or gel type batteries.
- Maximum charge current 300mA.
- Automatic switch over to stand-by battery.
- Battery short circuit protection (circuit breaker).
Additional Features:
- AC input and DC output LED indicators.
