KONE TAC5-1E Elevator TAC5 Series Drive Trigger Control Board
KONE TAC5-1E (OEM part number: 822003977 / KM357315G03) is a core thyristor firing drive board for KONE classic TAC5 elevator traction machine variable speed control systems, widely used in residential buildings, office towers, shopping malls and hospital passenger elevators equipped with traditional AC variable speed traction machines. KONE TAC5-1E receives speed operation commands from the main elevator controller, outputs precise trigger signals to drive power thyristor modules, realizes smooth elevator startup, speed regulation and leveling control, and integrates overcurrent, overheat and phase loss detection logic as an indispensable spare electronic component for maintaining normal operation of aging KONE TAC5 elevator control cabinets. Elevator maintenance technicians rely on KONE TAC5-1E to deliver stable speed loop control and reliable fault protection under long-running indoor cabinet environments.
