► Product Overview


The CXA-P1212B-WJL-1 7803 R high-voltage board (also known as an inverter board) is a key component designed specifically for the Philips IntelliVue MP50 patient monitor. As a dedicated CCFL (Cold Cathode Fluorescent Lamp) backlight inverter, this board powers the monitor's 12-inch color SVGA display. Its primary function is to convert the low-voltage DC power (typically 12V) from the monitor's mainboard into a stable high-frequency AC voltage (up to 1700V) to drive the dual CCFL backlight tubes inside the display. By providing a stable 2-8mA operating current, the board ensures that the screen emits uniform and stable light, resulting in clear display of vital signs waveforms, patient data, and system menus.
