It reduces AC 230V to AC 12V, providing outputs of 12V, 12V, and 0V. This transformer is ideal for hobbyists, students, and engineers building power supplies or audio amplifier circuits.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePrimary Voltage: 230V AC\u003c\/li\u003e\n\u003cli\u003eSecondary Voltage: 12V-0-12V AC (center tapped)\u003c\/li\u003e\n\u003cli\u003eCurrent Rating: 3 Amps\u003c\/li\u003e\n\u003cli\u003ePower Rating: 36 VA\u003c\/li\u003e\n\u003cli\u003eFlying colored insulated connecting leads (approx. 100 mm long)\u003c\/li\u003e\n\u003cli\u003eConstruction: General purpose chassis mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible with\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eArduino Uno, Mega, Nano\u003c\/li\u003e\n\u003cli\u003eESP32 and ESP8266 development boards\u003c\/li\u003e\n\u003cli\u003eRaspberry Pi (via regulated power supply circuit)\u003c\/li\u003e\n\u003cli\u003eSTM32 and other microcontroller boards\u003c\/li\u003e\n\u003cli\u003eAudio amplifier modules (e.g., TDA2030, LM1875)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat you can build with it\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eA dual-rail power supply for audio amplifier projects\u003c\/li\u003e\n\u003cli\u003eA regulated 12V DC power supply for microcontroller breadboards\u003c\/li\u003e\n\u003cli\u003eA battery charger circuit for 12V lead-acid batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBuilt and Backed by Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component from Compoden comes with an AI build companion — delivered via QR, email, or WhatsApp — that helps you wire and program this part into a working project.
