Transformer 0-12V 0.3A 3.6VA

The Transformer 0-12V 0.3A 3.6VA is a small step-down transformer with a 12 V AC secondary rated at 0.3 A, giving 3.6 VA of power. It is a good fit for low-power linear supplies that run timers, relays, small control boards and electronics kits: add a bridge rectifier and a filter capacitor to turn its output into DC for your circuit.

Transformer 0-12V 0.3A 3.6VA Specifications

• Output (secondary): 12 V AC between the 0 V and 12 V terminals
• Output current: 0.3 A (300 mA)
• Power rating: 3.6 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 0.3A 3.6VA Applications

• Small regulated supplies with a 7805 or 7809 regulator
• Powering relay, timer and control boards
• Doorbell, alarm and indicator circuits
• Electronics kits and school projects
• Replacement transformer in small appliances

What's in the Box

• 1 × transformer 0-12 V, 0.3 A, 3.6 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. Small transformers give a noticeably higher voltage at light load, so check that your regulator and capacitors are rated for it.
