Definitions
- the electrostatic guns have a PCB assembly potted into the smart handle. This PCB assembly is connected to the electrostatic power supply through a flex, cable.
- the PCB has a mioroprocessor that is programmed to senses both tip current and power supply reference voltage. The microprocessor then calculates tip voltage based on these inputs.
