Factory-Tested Reliability for Demanding Installations
A LED power supply failure on a completed project is costly — remedial access, downtime, replacement parts. The CD Series addresses this at source. Before any unit leaves the factory, it is run at 100% of its rated output wattage for a full-load burn-in period. This stress-tests every component under real operating conditions and screens out the early-life failures that cause drivers to fail within their first hours of use.
The result is a driver with a substantially lower field failure rate than comparable untested units. For commercial architects, lighting designers and electrical contractors, this matters: the CD Series is a driver you can install with confidence in a finished ceiling or inaccessible cove and expect it to keep running.
🔬 What a Burn-In Test Actually Does
Electronic component failures follow a bathtub curve — failure rates are highest at the very beginning of life (infant mortality) and again at end of life. A full-load burn-in test accelerates the infant mortality phase at the factory before the driver ships. Units that would fail in the first 50 hours of field use instead fail during the burn-in cycle and are removed. What reaches your installation has already survived its most vulnerable phase.
4-Gear DIP Switch Dimming — No External Controller
The CD Series includes a DIP switch bank on the driver body. Select one of four brightness levels before installation — the driver locks to that output and maintains it stably regardless of mains voltage fluctuation. No dimmer switch, 0-10V controller, Triac phase signal or DALI bus is required.
When to Use Gear Dimming vs. Continuous Dimming
Gear dimming is the right choice when a consistent, architect-specified brightness level is required and the brightness does not need to change dynamically by occupants or a BMS. Common applications: display lighting set to 75%, commercial cove preset to 50% for ambient, full-brightness task lighting at 100%.
If you need variable brightness controlled from a wall plate or building management system, the CP Series (Triac / 0-10V / PWM dimming) is the appropriate choice. The CD Series simplifies the installation by removing the dimmer circuit entirely — fewer components, fewer points of failure.
Slow Start — Selectable Soft On at Power-Up
When slow start is selected via the DIP switch, the output ramps up gradually from zero to the set brightness level at power-on, instead of switching instantly to full output. This prevents the abrupt glare flash that disrupts occupant comfort — critical in hotel rooms, bedrooms, galleries, restaurants and retail environments where the experience of turning the lights on matters as much as the end result. Instant-on mode is also selectable for task, emergency or switching applications where immediate full output is required.

⚖️ Sizing Guide — Always Apply the 20% Headroom Rule
Total your LED load wattage, then divide by 0.8 to find the minimum driver rating. Example: a 25-metre cove with 16W/m 24V strip = 400W load ÷ 0.8 = 500W minimum — choose the 500W model.
Running a driver continuously above 80% of rated load increases internal temperature, reduces efficiency, and shortens operating life. The headroom keeps the driver cool and extends its service years significantly.
