Overview
IEC 61800-1:1997, established by the International Electrotechnical Commission (IEC), specifies general requirements and rating specifications for low voltage adjustable speed d.c. power drive systems (PDS). This standard is applicable to general purpose d.c. drive systems comprising power conversion equipment, control systems, and motors. It is designed for systems connected to line voltages up to 1 kV a.c., at 50 Hz or 60 Hz, and explicitly excludes drives for traction and electric vehicles.
IEC 61800-1:1997 provides a comprehensive framework for the specification, performance evaluation, and application guidelines of adjustable speed electrical power drive systems. It focuses on system-level requirements rather than individual components, promoting performance consistency, safety, and international compatibility in industrial settings.
