  • Pin 1: VCC (12V DC Output)
  • Function: Provides a regulated 12V DC output to the load device.
  • Type: Output
  • Max Current: 10A
  • Connection: Connect to the positive terminal of the load device.
  • Pin 2: V- (GND, 0V DC)
  • Function: Provides a common ground connection for the power supply and load device.
  • Type: Output
  • Connection: Connect to the negative terminal of the load device.
  • Pin 3: AC_IN (L, Line) - Live Wire
  • Function: Connects to the live wire of the AC input power source (e.g., wall outlet).
  • Type: Input
  • Connection: Connect to the live wire of the AC power source (e.g., black wire in a standard IEC C13 power cord).
  • Pin 4: AC_IN (N, Neutral) - Neutral Wire
  • Function: Connects to the neutral wire of the AC input power source (e.g., wall outlet).
  • Type: Input
  • Connection: Connect to the neutral wire of the AC power source (e.g., white wire in a standard IEC C13 power cord).
  • Pin 5: FG (Fault Ground)
  • Function: Provides a fault ground connection for the power supply. This pin is internally connected to the chassis ground.
  • Type: Input
  • Connection: Typically not connected, but can be connected to the chassis ground of the load device for safety purposes.
  • Pin 6: ON/OFF (Remote On/Off Control)
  • Function: Allows remote control of the power supply's on/off state using an external signal.
  • Type: Input
  • Connection: Connect to a digital signal (e.g., from a microcontroller) to remotely turn the power supply on or off. A low signal (0V) turns the power supply off, while a high signal (e.g., 5V) turns it on.
  • Connection Structure
  • To connect the 12V 10A SMPS Power Supply to a load device, follow these steps:
  • 1. Connect Pin 1 (VCC) to the positive terminal of the load device.
  • 2. Connect Pin 2 (V-) to the negative terminal of the load device.
  • 3. Connect Pin 3 (AC_IN, L) to the live wire of the AC power source (e.g., black wire in a standard IEC C13 power cord).
  • 4. Connect Pin 4 (AC_IN, N) to the neutral wire of the AC power source (e.g., white wire in a standard IEC C13 power cord).
  • 5. If using remote on/off control, connect Pin 6 (ON/OFF) to the digital signal output of the controlling device (e.g., microcontroller).
  • 6. Ensure proper electrical isolation and safety precautions when working with AC power sources and high-current DC outputs.
  • Note: Always refer to the power supply's datasheet and user manual for specific connection diagrams and safety guidelines.
