7-12 高頻放電線圈

說明：

High-Frequency Coil

Perfect to Excite Electrical Tubes for Demonstrations

Use this 30cm long High-Frequency Coil to test vacuum equipment for leakage or to excite electrical tubes for demonstrations. The Teslatype high-frequency coil is mounted in a hard Bakelite case, sized so you can hold it in one hand. One terminal of the secondary is attached to the pointed end of the coil. A screw at the large end lets you adjusts it as you need. The voltage is 40-50kV and the spark frequency is 3 to 4 MHz. The spark length is adjustable by turning a knob. You will need to turn the unit off after 10 minutes of continuous use to cool. It comes with a connecting cord and attachment plug, for use on 115 VAC. 50/60 Hz. Includes instructions.
