SMP3 - Power Supply/Charger

Overview:

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.

Specifications:

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.

Extremely compact design.

Includes battery leads.

Snap Track compatible (order Altronix model #ST3).

DIN Rail Mount version available (order Altronix model #DPS3).

Board Dimensions (W x L x H approximate):

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

* Specified at 25˚ C ambient.

Installation Instructions:

The SMP3 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.

1.Mount the SMP3 in the desired location / enclosure.

2.Set DC output voltage with switches (refer to Voltage Output/Transformer Selection Table).

3.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).

4.Measure output voltage before connecting devices. This helps avoiding potential damage.

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.
