Murata MPH3211/PCPH0294 DC Output Board AZ320139

Murata MPH3211 / PCPH0294 (Board ID: AZ320139) is a high-voltage DC output board, likely used in printers, copiers, or other imaging devices requiring precise, low-current, high-voltage output—such as corona charging or transfer functions in electrophotographic processes. Description: This board steps up voltage through a transformer-based circuit and outputs regulated high-voltage DC. It includes safety insulation and warning labels due to the presence of voltages up to 6.2 kV. It is built around Murata's high-frequency HV module (MPH3211W) and includes discrete filtering and feedback components for voltage regulation.
