ITW Ransburg A12311-00 High Voltage Controller

ITW Ransburg A12311-00 High Voltage Controller is the compact, microprocessor-based power unit that drives Ransburg electrostatic coating cascades, providing a controlled high-voltage supply to the spray applicator. It accepts 24 VDC input (24VDC ±0.5 V) at about 2.5 A and supports Local or Remote operation with either Voltage Mode or Current Mode high-voltage output, enabling precise voltage or current control for varied coating processes. The controller is housed in a compact package measuring 5.5 inches tall by 7.5 inches wide by 3.5 inches deep and is designed to work with cascades such as A12295-00 or A12296-00; it continuously monitors voltage and current to maintain the setpoint while providing built‑in diagnostics. Operating in a factory environment, it tolerates 0°C to 55°C (storage -40°C to 85°C) and up to 95% relative humidity non-condensing, making it suitable for industrial spray booths and automated coating lines where stable HV supply and feedback are critical.
