Edwards SCU-800 Turbo Molecular Pump Control Unit

The Edwards SCU-800 (Part Number: YT49-Z3-Z20) is a fully digital, universal control unit designed for magnetically suspended turbomolecular pumps. Built to support medium-capacity STP series turbo pumps, the SCU-800 incorporates Auto Vibration Reduction (AVR) and Auto Balancing System (ABS) technologies to minimize rotational vibration and deliver consistent, ultra-high vacuum performance.

This controller features standard serial communication interfaces (RS-232/RS-485), advanced predictive maintenance alerts, and compliance with international semiconductor safety standards including CE, UL, and SEMI S2.

Technical Specifications

Compatible Turbo Pump Series

The SCU-800 serves as a universal controller for middle-sized Edwards and Seiko Seiki Maglev turbomolecular pumps:

• STP-603 / STP-1003 Series

• STP-H301 / STP-H451 / STP-H803 / STP-H1303 Series

• STP-A803C / STP-A1303 / STP-A1603 Series

Key Features & Lab Benefits

• Universal Compatibility: A single SCU-800 controller supports multiple middle-sized pump models, simplifying backup equipment inventories in multi-pump laboratory setups.

• Active Vibration Suppression: Embedded Auto Vibration Reduction (AVR) dynamically balances the magnetic bearing suspension during acceleration and steady-state operation.

• Predictive Diagnostics: Advanced pre-maintenance functions track run hours, rotor stability, and thermal loads to give notice prior to scheduled maintenance cycles.

• Dual Serial Communication: Integrated RS-232 and RS-485 ports enable concurrent connection to local PC interfaces and automated fab-wide monitoring systems.
