SATEL APS-412 Backup power supply
Power supply
The APS-412 switching power supply is designed for powering 12 VDC devices. It is provided with a connector for integration with SATEL devices.
Description
-
F1 fuse (T 3.15 A) – AC circuit protection.
-
LEDs to indicate the power supply status:-
red LED:
OFF – current consumption not exceeding 4 A, flashing – current consumption exceeding 4 A. -
yellow LED:
ON – battery OK or the battery testing mode disabled, flashing – low battery (battery voltage below 11.5 V), OFF – no battery or blown F3 fuse. -
green LED:
ON – AC power OK,
flashing – no AC power or blown F1 fuse.
-
part of the electronics board visible after the cover is removed.
Description of terminals
- L – terminal for connecting phase conductor.
- N – terminal for connecting neutral conductor.
- PE – terminal for connecting protective conductor.
- +12V – +12 VDC power output.
- COM – common ground.
- WS – OC type output signaling 230 VAC power loss.
- WB – OC type output signaling low battery voltage (below 11.5 V).
- WP – OC type output signaling current overload (above 4 A).
Configuration
The switch 6 must be set in OFF position.
The switches 1-5 are used for configuring the following power supply operating
parameters:
- Switch 1 – audible trouble signaling: ON=enabled / OFF=disabled.
- Switch 2 – battery test: ON=enabled / OFF=disabled.
| AC power failure reporting delay | |
|---|---|
| Switch | 3 s |
| 4 | OFF |
| 5 | OFF |
Installation
Disconnect power before making any electrical connections. Do not connect deeply discharged battery to the power supply (with voltage across unloaded terminals below 11.5 V). The used batteries must not be discarded, but should be disposed of in accordance with the existing rules for environment protection.The power supply should be permanently connected to the 230 VAC mains supply. Make sure that the circuit you select will always be alive and protected with a proper safety device. As the emergency power supply source, use a 12 V sealed lead-acid battery or other 12 V battery with similar charging characteristics. The battery capacity must be selected to match the current consumption in the system.
- Remove the cover of power supply terminals (Fig. 5).
- Use the DIP-switches (see Fig. 2) to configure the power supply.
- If the connector for supplying power to SATEL devices is to be used, connect to it the cable shown in Fig. 4 (Fig. 6).
- If screw terminals are to be used for supplying power to devices, screw the wires to +12V and COM terminals.
- Connect the battery wires (Fig. 3) to the connector on the electronics board (Fig. 7).
- You can connect the trouble signaling outputs with control panel zones, or you can connect e.g. LEDs to these outputs.
- Run the 230 VAC power cable through the cable gland (Fig. 8).
- Screw the 230 VAC power wires to terminals: phase conductor to L terminal, neutral conductor to N terminal, and protective conductor to PE terminal (Fig. 9).
- Screw the element fastening the 230 VAC power cable (Fig. 10).
- Replace the cover of power supply terminals (Fig. 11) and fasten it with a screw (Fig. 12).
- Connect the battery to the dedicated wires (battery positive to red wire, negative – to black).
- Turn on 230 VAC power. When the AC power is present, the power supply will signal it with
When no longer in use, this device may not be discarded with household waste. Electronic equipment should be delivered to a specialized waste collection center. For information on the nearest waste collection center, please contact your local authorities. Help to protect the environment and natural resources by sustainable recycling of this device. Improper disposal of electronic waste is subject to fines.
