Altronix DPS1 Power Supply-Charger
Overview
DPS1 power supply/charger converts low voltage AC input into 6VDC or 12VDC @ 1.2A or 24VDC @ 750mA 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

(Altronix model TP1220)
Installation Instructions
-
Mount the DPS1 using included ST3 snap track and clips:
- Slide the board into the outermost slots on the ST3 (Fig. 2, pg. 2);
- Attach the clips to the back of ST3 using provided guides and slots;
- Mount the DPS1 onto the DIN rail using the clips (Fig. 2, pg. 2).
-
The unit is factory set for 12VDC. For 6VDC output cut jumper J2, for 24VDC output cut Jumper J1.
-
Connect the proper transformer to terminals marked [AC] (refer to 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 (AC Input, Battery Wires). Minimum 0.25” spacing must be provided. -
Measure output voltage before connecting devices. This helps avoid potential damage.
-
Devices to be powered should be connected to terminals marked [+ DC] and [DC – BAT], carefully observing polarity (Fig. 1, pg. 2).
-
Connect battery to terminals marked [BAT +] and [DC – NEG] (battery leads included) (Fig. 1, pg. 2). Use two (2) 12VDC batteries connected in series for 24VDC operation.
Note: When batteries are not used, a loss of AC will result in a loss of
output voltage.
LED Diagnostics
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating condition. |
| ON | OFF | Loss of AC. Stand-by 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 (refer to Voltage Output/Transformer |
Selection Table).
+ DC –| 6VDC-12VDC @ 1.2A continuous supply current. 24VDC @ 750mA continuous
supply current.
– BAT +| Stand-by battery connections. Maximum charge rate 300mA.
