Fanuc Inverter PCB Board for 0i-B/ 0i Mate-B/ 16i/ 18i/ 21i A14L-0143-0002

📌 FANUC A14L-0143-0002 — Inverter Module (LCD Inverter)

• Part Number: A14L-0143-0002 (often also seen with suffixes such as #A or #B-R)

• Manufacturer: FANUC (industrial automation & CNC control systems maker)

• Type: Electronic inverter board/module for display systems

• Function: DC/AC inverter specifically used to power the backlight or display inverter circuitry of a CNC or industrial LCD panel, often associated with 15-inch LCD screens in FANUC panels.

• Application: Internal component in monitors or operator interface units of FANUC controllers — it converts DC power to the AC power needed by the LCD panel’s backlight section.

• Category: A14L series parts, which include power supply and inverter boards used in FANUC automation control systems.

🛠️ Typical Usage

This board is typically replaced when the display backlight of an HMI or CNC panel fails (e.g., dim or no backlight) or when the inverter part of the display assembly stops functioning. It’s not a standalone device — it’s a PCB sub-assembly that sits inside the display unit.
