Transformer 0-12V 3.33A 40VA

The Transformer 0-12V 3.33A 40VA is a step-down transformer with a 12 V AC secondary rated at 3.33 A, giving 40 VA of power. It is a common building block for linear power supplies, battery chargers and audio amplifiers: add a bridge rectifier and a filter capacitor to turn its output into DC for your circuit.

Transformer 0-12V 3.33A 40VA Specifications

• Output (secondary): 12 V AC between the 0 V and 12 V terminals
• Output current: 3.33 A
• Power rating: 40 VA
• Input (primary): mains AC; check the label for the rated input voltage
• Type: step-down mains transformer
• DC after rectifying: roughly 15–16 V with a bridge rectifier and smoothing capacitor at light load

Transformer 0-12V 3.33A 40VA Applications

• 12 V linear power supplies with a voltage regulator
• Lead-acid battery chargers
• Audio amplifier power supplies
• Powering 12 V AC lamps and devices
• Lab, school and repair projects

What's in the Box

• 1 × transformer 0-12 V, 3.33 A, 40 VA

Tip: The primary connects to mains voltage, so insulate all terminals, fit a fuse on the primary side and only work on it with the power off. For a stable DC output, follow the rectifier and capacitor with a voltage regulator rated for your load current.
