Pfeiffer Vacuum TC 600 Electronic Drive Unit / Turbo Pump Controller

The Pfeiffer TC 600 is a highly reliable, vintage micro-processor-controlled electronic drive unit designed to power, monitor, and regulate Pfeiffer standard and Compact TurboDrag™ molecular vacuum pumps (such as the TMH/TMU 261, 330, and 521 series).

The TC 600 serves as the smart brain of the pumping system, managing complex operating sequences including dynamic rotor acceleration, automatic venting control, system heating, and sealing gas valve regulation. Equipped with integrated RS-485 serial communication, it provides high-precision data readouts for operating parameters, run-time data, and comprehensive fault diagnostics, making it an essential component for automated industrial, coating, and laboratory vacuum systems.

• Common Manufacturer Part Numbers: PM C01 720 / PMC01720

• Alternative Core Variants: PM C01 690 / PMC01690 (including "A" and "C" variants)
