Kintronic Labs manufactures a complete line of single pole, double throw or double pole, double throw RF contactors ranging in current rating from 40A to 200A and in voltage rating from 20kV to 80kV. The RF contactors with current rating between 40A and 100A utilize solenoid drive requiring a short duration 110VAC or 220VAC pulse. Solenoids are available such that AC voltage can be field changed between 110 and 220 VAC. The RF contactors rated for 100A or higher utilize a DC linear actuator that requires a separate drive circuit to convert AC to DC drive.
