GB/T 42325-2023Electrical interface specification for phase-cut dimmer in phase-cut dimmed lighting systems (English PDF)

1 Scope

This document specifies the electrical interface and test procedures for controlling the brightness of mains-powered electronic lighting equipment using mains voltage phase-cut dimmers

These devices are intended to be controlled by mains voltage phase-cut dimmers, such as LED integrated lamps and light sources with external control gear:

This document applies to the electrical interface of phase-cut dimmers in phase-cut dimming lighting systems:

A similar circuit using a phase-cut dimmer but not including an electronic switch with adjustable phase-cut angle is implemented with reference to the same phase-cut dimmer:

Safety requirements are not included in this document, but are included in the respective product standards:
