Pin Configuration

  • Component Name: 12-0-12 Transformer-500mA
  • Description: The 12-0-12 Transformer-500mA is a step-down transformer designed for use in low-voltage AC-DC power supplies. It has a primary voltage rating of 12V, a secondary voltage rating of 12V, and a maximum current rating of 500mA.
  • Pinout:
  • The transformer has six pins, labeled as follows:
  • Primary Side:
  • 1. Pin 1: Primary Positive (Vp): This pin is connected to the positive terminal of the primary voltage source (12V).
  • 2. Pin 2: Primary Negative (Vn): This pin is connected to the negative terminal of the primary voltage source (0V or neutral).
  • Secondary Side:
  • 1. Pin 3: Secondary Positive (Vs): This pin provides the positive output voltage (12V) to the load.
  • 2. Pin 4: Secondary Negative (Vs): This pin provides the negative output voltage (0V or neutral) to the load.
  • 3. Pin 5: Center Tap (CT): This pin is connected to the center tap of the transformer's secondary winding. It provides a neutral reference point for the output voltage.
  • 4. Pin 6: No Connection (NC): This pin is not connected internally and should be left unconnected.
  • Connection Structure:
  • To connect the pins properly, follow this structure:
  • Primary Side:
  • Connect Pin 1 (Vp) to the positive terminal of the primary voltage source (12V).
  • Connect Pin 2 (Vn) to the negative terminal of the primary voltage source (0V or neutral).
  • Secondary Side:
