Current and Voltage Contol

 

ITEM DESCRIPTIONPRICE CONTACT

This is a Bennett C-835 controller that has been completely reworked for use in HV projects. It has had all unnecessary peripheral compenents removed has been rewired. It may be used as an autotransformer at either 120 or 240 VAC in and output 30% over line voltage. By placing the unit in series in a circuit, it may also be used as an ajustable ballast inductor with over 100 settings for fine current control between 1.4 and 30 Amps on a 120 Volt line or 2.8 and 60 Amps on a 240 Volt line. $199.95

This is a Continental brand controller that has not been reworked. It is designed to control the input voltage and current to a 125 kV, 200 ma high voltage generator. It contains an autotransformer and all kinds of useful switches, transformers, capacitors, meters, high current rotary tap switches, resistors, relays, etc. $89.95 Carl


This is a Universal brand controller that has been partially reworked. It is designed to control the input voltage and current to a 25 kV, 20 ma high voltage generator. It contains an autotransformer connected to a rotary tap switch, a high current breaker switch, a timer switch with many high precision resistors, a large Ohmite rotary adjustable resistor, and other small components. $49.95 Carl

This is a York controller that has been completely reworked for use in HV projects as a variable voltage power supply. It contains a 96 lb autotransformer connected to 2 high current rotary tap switches mounted to the front plate. It is rated at 100 Amps 240 VAC. The unit has been custom designed and built to be used like a 280 Volt 100 Amp Variac - if there were such a thing. Each of the 8 settings on the Major tap switch increases the output by 30 Volts and then there are 10 3-Volt incremental increases with the Minor tap switch. Therefore, there are 80 voltage settings. The minimum output voltage is 56 VAC and the maximum is 281 VAC on a 240 Volt line. It could also be used on a 120 VAC line and the outputs would be half that shown on the chart. By placing the unit in series in a circuit, it may also be used as an ajustable ballast inductor. Used in this manner, the 80 settings would adjust the inductance of the ballast to control current. At its lowest setting, the inductance is 3.4 millihenries all the way to a full scale value of 85.6 Millihenries. A 240 Volt line would be regulated from 7.4 Amps to 188 Amps - and half of these numbers for 120 Volts. $139.95
