Center Tapped Step Down Transformer 220V 9V-0-9V 1A
A Center Tapped Step Down Transformer 220V 9V-0-9V 1A is a dual 9VAC output with a center tap (0V), providing 9V-0-9V at 1A current capacity. It is commonly used in power supplies, rectifiers, and low-voltage AC applications. The center tap allows for both 9V and 18V rectified outputs, making it ideal for DC power circuits, amplifiers, and embedded systems.
Features
- Dual Voltage Output where Provides 9VAC or 18VAC (by combining both 9V outputs) for flexible applications.
- Converts high-voltage AC (220V) to a lower, safer voltage (9VAC), ensuring reliable operation of electronic circuits.
- With a 1A current rating, it can power moderate-load applications like amplifiers, control circuits, and regulated power supplies.
- The center tap allows for better voltage regulation and balancing in circuits requiring both positive and negative DC rails.
- The transformer provides galvanic isolation between the primary (high-voltage side) and secondary (low-voltage side), enhancing safety by reducing the risk of electric shock.
- Used in audio amplifiers, industrial controls, battery chargers, and microcontroller-based circuits that require dual voltage rails.
