Transformer 0-18V 0.417A 7.5VA

The Transformer 0-18V 0.417A 7.5VA is a step-down transformer with an 18 V AC secondary rated at 0.417 A, giving 7.5 VA of power. It suits low-power linear supplies for control boards, small amplifiers and electronics kits that need 12 V to 15 V DC: add a bridge rectifier, a filter capacitor and a regulator to turn its output into stable DC.

Transformer 0-18V 0.417A 7.5VA Specifications

• Output (secondary): 18 V AC between the 0 V and 18 V terminals
• Output current: 0.417 A (417 mA)
• Power rating: 7.5 VA
• Input (primary): mains AC; check the label for the rated input voltage
• Type: step-down mains transformer
• DC after rectifying: roughly 23–25 V with a bridge rectifier and smoothing capacitor at light load

Transformer 0-18V 0.417A 7.5VA Applications

• Regulated 12 V or 15 V supplies with a 7812 or 7815 regulator
• Small audio amplifier and preamplifier supplies
• Powering relay, timer and control boards
• Electronics kits and school projects
• Replacement transformer in small appliances

What's in the Box

• 1 × transformer 0-18 V, 0.417 A, 7.5 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. Use smoothing capacitors rated for at least 35 V, because the rectified DC is well above 18 V.
