Integrated drive solutions for high-precision operation

March 18, 2024

With great enthusiasm we're unveiling the next generation of motorized Vacuum Capacitors ensuring highest accuracy. Equipped with the latest controller technology, Comet's integrated drive systems are designed to reach high precision capacitance control.

Comet motorized capacitors offer the latest integrated drive technology for Vacuum Capacitors at best price-performance ratio. A single communication protocol for RS232 and RS485 provides flexibility in a wide range of applications.

 

Motorized Capacitors are the ideal solution for high-precision operation. Besides ensuring highest accuracy, motorized capacitors simplify procurement with an easy-to-install subsystem.

The core component of the Universal Motorized Capacitor is a Comet variable Vacuum Capacitor, mounted with an insulating cover, coupler and stepper-motor. A durable, backlash-free Comet-coupler connects the capacitor to the drive system. Integrated flanges ensure easy mounting in the system. Appropriate high-voltage insulation between the capacitor and motor flange is also included.
