Technology overview
Phase Cut Dimming for Modern LED Lighting
Phase-cut dimming controls delivered power by altering part of the AC waveform. It is commonly associated with leading-edge and trailing-edge dimmers used in lighting and automation systems.
Compatibility depends on the driver, dimmer topology, connected load, wiring and operating conditions, so it must be evaluated for the selected model and application.
Control methods
Leading-Edge and Trailing-Edge Dimming
Leading-Edge Dimming
Leading-edge control removes the beginning of each AC half-cycle. Driver and load compatibility must be confirmed.
Trailing-Edge Dimming
Trailing-edge control removes the end of each AC half-cycle. It is commonly considered for electronic lighting loads, subject to the driver, dimmer and application.

Technical questions
Frequently Asked Questions
What is a phase cut dimmable LED driver?
It is an LED driver designed to interpret compatible phase-cut control on the AC input and regulate LED light output. Performance depends on the driver, dimmer and connected load.
What is the difference between leading-edge and trailing-edge dimming?
Leading-edge control cuts the beginning of each AC half-cycle, while trailing-edge control cuts its end. The correct topology depends on the dimmer, driver design and application.
Is a TRIAC dimmable driver the same as a phase-cut driver?
In common lighting use, TRIAC wall dimmers use phase-cut (leading-edge) control. JSK URJA published phase-cut drivers are specified for leading-edge and trailing-edge compatibility. The dimmer, load and wiring must still be checked.
What is the verified minimum dimming level on published phase-cut models?
Published phase-cut models specify 1–100%. This website does not claim 0% dimming or dim-to-off.
Does JSK URJA manufacture phase cut LED drivers in India?
JSK URJA develops phase-cut dimmable-driver solutions through its in-house R&D and production capabilities in India. Published model JUNCTD15N5Y is listed on this page. Additional models appear only after verification and approval.
