1 Scope

This document specifies the rated values, operating conditions, technical specifications, and other requirements of general variable frequency speed control equipment (hereinafter referred to as "speed control equipment") of 1 kV and below.

Requirements, test item requirements and marking, packaging, transportation and storage.

This document is applicable to power supplies with rated input voltage of 1 kV AC and 1.5 kV DC and below, rated input frequency of 50 Hz or

Design, production and installation of speed regulating equipment with an output voltage not exceeding 1 kV and an output frequency less than 600 Hz.

Note. Speed regulating equipment with rated input voltage of 1 140 V or output frequency greater than 600 Hz is also usually implemented in accordance with this document.

To be determined through negotiation between the manufacturer and the user.
