H19 overview
The H19 is a dimmable constant-current (CC) LED driver rated 10-52W, with a 9-48V output window and IP20 protection. Dimming options: DALI / 0-10V / Triac (phase-cut) / DIP-switch dimming. Typical applications: downlights and spotlights.
Part of the H Series (Smart Dimming), it is built with pure copper transformer, full rated output, flicker-free. Every unit is factory tested; we recommend you keep 10–20% headroom on the set current to limit junction temperature and extend service life.

H19 FAQ
Which dimming protocols does the H19 support?
It supports DALI / 0-10V / Triac (phase-cut) / DIP-switch dimming. 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.Is the H19 constant current or constant voltage, and how do I match the load?
It is a constant-current (CC) driver rated 10-52W with a 9-48V output window. Match the window against the actual forward voltage of your LED string and keep 10–20% headroom on the set current. Protection rating is IP20.Where can the H19 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 H19 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.
