| In October'99 I made this control box, in order to have more safety, power filters and instruments for my coiling activities. The TC variacs, ballasts, transformers are not enclosed in the box, but can be connected in a flexible way to the backside. An old wattmeter could be equiped with shunts and pre-resistors to cover a broad range of power situations. The box also contains low voltage power sources for laboratory use (12/24V-30A AC and 34/17V-30A DC). |
