Product Overview
The Electrostatic Spray Gun High Voltage Module Series is designed for modern electrostatic powder coating and liquid spraying systems. The module is the core high-voltage generation unit inside the spray gun, responsible for converting low input voltage into stable high DC voltage for efficient electrostatic charging of powder or coating particles.
These modules adopt a multistage voltage multiplication structure (cascade HV circuit) with high insulation materials, ensuring stable output, strong discharge performance, and long service life in industrial environments.
They are widely used in:
* Electrostatic powder coating guns
* Automatic spray coating systems
* Manual electrostatic spray guns
* Industrial finishing equipment
* Automotive parts coating lines
Product Structure & Working Principle
This series typically includes:
* High-voltage cascade multiplier circuit
* Precision high-voltage resistors
* Fast recovery diodes
* Insulated epoxy sealing structure
* Output electrode needle / discharge tip connection
Working principle:
Low-voltage input →rectification → multi-stage voltage multiplication → DC high voltage output → electrostatic field generation at spray nozzle.
This ensures strong and uniform electrostatic adsorption for powder particles, improving coating efficiency and reducing material waste.
