GB/T 30844.2-2024Variable-frequency drive of 1 kV and below - Part 2: Test methods (English PDF)

1 Scope

This document describes the test methods for general purpose variable frequency speed regulating equipment (hereinafter referred to as "speed regulating equipment") of 1 kV and below.

This document is applicable to rated input voltage of 1 kV AC and 1.5 kV DC and below, rated input frequency of 50 Hz or 60 Hz,

Inspection and acceptance of speed regulating equipment with output voltage not exceeding 1 kV and 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.
