How to Use Power Supply Charger, Single Fused Output, 12VDC @ 10A, 115VAC, Board: Examples, Pinouts, and Specs

The Altronix AAL1012ULXB is a high-performance power supply charger designed to deliver a regulated 12VDC output at up to 10A. It operates on a 115VAC input and features a single fused output for enhanced safety and reliability. This component is ideal for powering and charging 12VDC devices, including security systems, access control systems, and other low-voltage electronics.

• Security and surveillance systems
• Access control systems
• Alarm systems
• General-purpose 12VDC power supply for electronics
• Battery charging for backup power systems

The AAL1012ULXB features terminal blocks for input, output, and battery connections. Below is the pin configuration:

1. Input Connection:

   • Connect the 115VAC input to the L (Live), N (Neutral), and G (Ground) terminals of the input terminal block.
   • Ensure proper insulation and secure connections to avoid electrical hazards.

2. Output Connection:

   • Connect the load (e.g., security system, access control device) to the + and - terminals of the output terminal block.
   • Verify that the load does not exceed the 10A current rating.

3. Battery Connection (Optional):

   • Connect a 12V sealed lead-acid battery to the BAT+ and BAT- terminals.
   • This allows the power supply to charge the battery and provide backup power in case of an AC power failure.

4. Power On:

   • After all connections are secure, power on the unit by supplying 115VAC to the input terminals.
   • The power supply will regulate the output voltage to 12VDC and charge the connected battery if applicable.

• Always ensure the input voltage matches the specified 115VAC rating.
• Use appropriately rated wires for input, output, and battery connections.
• Replace the fuse with a 10A fuse of the same type if it blows.
• Avoid overloading the power supply by connecting devices that exceed the 10A output current rating.
• Ensure proper ventilation around the power supply to prevent overheating.
• If using a battery, periodically check its condition and replace it as needed.

While the AAL1012ULXB is not directly programmable, it can be used to power an Arduino UNO and its peripherals. Below is an example of how to connect the power supply to an Arduino UNO:

1. Connect the + terminal of the power supply output to the Arduino's VIN pin.
2. Connect the - terminal of the power supply output to the Arduino's GND pin.

Here is a simple Arduino sketch to blink an LED using the power supply:

// This sketch blinks an LED connected to pin 13 of the Arduino UNO.
// Ensure the Arduino is powered by the AAL1012ULXB power supply.

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. Can I use this power supply with a 24VDC device?

   • No, this power supply is designed for 12VDC devices only.

2. What type of battery is compatible with this power supply?

   • It supports 12V sealed lead-acid batteries.

3. How do I know if the fuse is blown?

   • If there is no output voltage and the input connections are correct, check the fuse and replace it if necessary.

4. Can I use this power supply outdoors?

   • No, this power supply is not weatherproof and should only be used in indoor environments.

5. What happens if the load exceeds 10A?

   • The fuse will blow to protect the power supply and connected devices. Replace the fuse after reducing the load.

By following this documentation, users can safely and effectively utilize the Altronix AAL1012ULXB power supply charger in their applications.
