Power Supply/Charger
Installation Guide
Overview:
Altronix SMP5 power supply/charger converts a 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:
Input:
- 16VAC to 28VAC
(Voltage Output/Transformer Selection Table).
Output:
- 6VDC, 12VDC, or 24VDC selectable output.
- 4A supply current.*
- Filtered and electronically regulated outputs.
- Short circuit and thermal overload protection.
Visual Indicators:
- AC input and DC output LED indicators.
Battery Backup:
- Built-in charger for sealed lead acid or gel-type batteries.
- Maximum charge current 0.3A.
- Zero voltage drop when switching over to battery backup.
Features:
-
Extremely compact design.
-
Includes battery leads.
-
Snap Trac compatible
(order Altronix model number ST3).
Board Dimensions (W x L x H approx.):
3” x 3.5” x 2” (76.2mm x 88.9mm x 50.8mm) -
Specified at 25˚C ambient.
Voltage Output/Transformer Selection Table:
Output
Voltage| Switch Position| Transformer Requirements
(Recommended Altronix Part #’s)
---|---|---
SW1| SW2
6VDC| ON| OFF| 16VAC / 40VA (TP1640)
12VDC| OFF| OFF| 24VAC or 28VAC / 100VA (-2428100), 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.
-
Mount the SMP5 board in the desired location/enclosure (mounting hardware included).
-
Set DC output voltage with switches (Voltage Output/Transformer Selection Table).
-
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). -
Measure output voltage before connecting devices. This helps avoid 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. -
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.
LED Diagnostics:
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating conditions |
| ON | OFF | Loss of AC. The standby battery is supplying power. |
| OFF | ON | No DC output. Short circuit or thermal overload condition. |
| OFF | OFF | No DC output. Loss of AC. Discharged or no battery present. |
Terminal Identification:
Terminal
Legend| Function/Description
---|---
AC/AC| Low voltage AC input (see voltage output/transformer selection table).
For 6VDC output use 16VAC or higher with a 40VA power rating or higher. For
12VDC output use 16VAC or higher with an 85VA power rating or higher. For
24VDC output use 28VAC with 175VA power rating or higher. Caution: Do not
apply voltage above 28VAC or 45VDC (maximum input rating).
+ DC —| 6VDC, 12VDC, or 24VDC @ 4A continuous supply current.
+ BAT —| Stand-by battery connections. Maximum charge rate 300mA.
