ABB 86466-18S Programmable Logic Controller Module

86466-18S, also cataloged as 8646618S, is a rectifier stack assembly from ASEA BROWN BOVERI that was used in legacy ABB drive systems to convert AC input into DC power for the drive's power electronics, typically forming the rectifier stage of the inverter or DC bus within older motor controllers. The part number 86466-18S / 8646618S is listed in distributor catalogs as a Rectifier Stack and it carries a weight of 3.18 kg, reflecting its compact yet heavy-duty power component. Discontinued by the manufacturer, this module is now available primarily through surplus or refurbished inventory channels, with availability depending on market supply. For engineers and technicians maintaining older ABB/ASEA BROWN BOVERI equipment that used this module, the 86466-18S may be encountered as a replacement option in the secondary market, where verified stock may include accompanying documentation or hardware from select distributors.
