K03 overview
The K03 is a dimmable constant-voltage (CV) LED driver rated 60-400W, with 12V / 24V output and IP20 protection. Dimming options: DALI. Typical applications: commercial and damp-environment lighting.
Part of the K Series (Half-Potted Dimming), it is built with potted construction, ultra-slim body, pure copper transformer, full rated output, flicker-free. Every unit is factory tested; we recommend you keep the connected load at or below 80% of rated power to preserve thermal margin and extend service life.

K03 FAQ
Which dimming protocols does the K03 support?
It supports DALI. Wiring must match the controller: Triac needs a leading- or trailing-edge dimmer, 0-10V needs a controller with a 0-10V output, and DALI requires a DALI bus with addressed drivers. We recommend testing a sample for dimming compatibility before a bulk order.What are the power range, output voltage and protection rating of the K03?
Rated 60-400W, output 12V / 24V, protection IP20. For constant-voltage drivers we recommend keeping the connected load at or below 80% of rated power — it lowers case temperature and extends life.Where can the K03 be installed?
Protection rating IP20: indoor dry locations — ideal inside fixtures, panels and control cabinets; dust-tight but not water-resistant. For outdoor or high-humidity installations, compare with the YFX S Series waterproof range.Does the K03 come with certification, warranty and samples?
Certification documents are provided per batch on request. 3-year warranty, factory-direct supply. Free samples for dimming and thermal testing; non-standard power, housing size and cable length can be customised. Pricing and lead time are quoted per order — call or WeChat +86 138 2356 2421.
