Abb CU930B

ABB CU930B is a high-voltage electrostatic spraying generator (Cascade Unit) used in ABB robotic paint application systems. It works together with ABB's high-voltage controllers (such as the RGH930/931 series) to generate the high-voltage DC required for electrostatic coating processes in automotive and industrial painting applications.

Technical Description

The CU930B functions as a voltage multiplication unit within ABB's electrostatic painting system. It receives a controlled low-voltage AC signal from the high-voltage controller and converts it into high-voltage DC output through an internal transformer and voltage multiplier circuit. This high voltage is then applied to the paint applicator, improving paint transfer efficiency and coating quality.
