WDTCC-08/10/12/15-TRIAC
Triac Phase-Cut Dimming
Leading & Trailing Edge
Triac dimming uses phase-cut technology to control brightness directly through the AC mains. Supports both leading-edge (front-cut) and trailing-edge (rear-cut) dimming — maximum compatibility with the wall dimmers already installed on site, with no control bus and no commissioning required.
Front-Cut Phase
Leading Edge — Traditional Triac
Standard Triac / incandescent wall dimmers. Ideal for retrofit and renovation projects where the existing dimmer stays in place.
Rear-Cut Phase
Trailing Edge — Electronic ELV
Electronic / MOSFET dimmers giving smoother, silent low-level dimming for hotels, restaurants and premium retail.
Triac vs DALI vs 0–10V — Which Should You Choose?
No DALI addressing — simpler wiring, no commissioning required. Flicker-free deep dimming with stable wired signal and zero interference.
| Feature | Triac (This Product) | DALI | 0–10V |
|---|---|---|---|
| Dimming Method | Phase-cut (Leading & Trailing) | Digital addressing | Analog 0–10V signal |
| Control Wire | 2-wire — uses existing mains | Requires DALI bus | Requires 2 extra low-voltage wires |
| Addressing / Commissioning | None required | Addressing + commissioning needed | None required |
| Group / Scene Control | Local, per-circuit | Full scene & group control | Zone control by circuit |
| Installed Cost | Lowest | Highest | Medium |
| Best For | Hotels, restaurants, retail, retrofit | Offices, malls, BMS integration | Commercial projects with analog control |

Dimensions & Installation
⚠️Installation notes: IP20 rated for indoor luminaires. Install in a ventilated position with clearance for heat dissipation; do not cover or seal the driver. Wiring must be carried out by a qualified electrician with mains power disconnected. Match the driver's constant current to the LED load and observe DC output polarity. For damp or outdoor locations, ask us about higher IP-rated options.

FAQ – Triac Dimmable Constant Current LED Driver 8W–15W
Does this driver support both leading edge and trailing edge dimmers?
Yes. It supports both leading-edge (front-cut) and trailing-edge (rear-cut) dimming, so it adapts to the wall dimmer already installed on site — no dimmer replacement needed.
What is the difference between front-cut and rear-cut dimming?
Front-cut (leading edge) cuts the rising edge of the AC waveform and is the traditional Triac dimmer type; rear-cut (trailing edge) cuts the falling edge and is electronic, giving smoother and quieter low-level dimming.
Which output current should I choose — 200, 250, 300 or 350 mA?
Match the driver current to your LED board's rated forward current. Send us the LED forward voltage and target current and we will recommend the right 8W, 10W, 12W or 15W model.
Can I use my existing dimmer brands?
The drivers offer excellent compatibility with global Triac dimmer brands. Share your dimmer brand and model list and we validate compatibility with samples before mass production.
Is the 8W–15W Triac driver suitable for outdoor use?
This series is rated IP20 and designed for indoor luminaires. For damp or outdoor locations, ask us about higher IP-rated options for your project.
Do you offer OEM/ODM and private label service?
Yes. We support OEM & ODM customization for voltage, current and size, including private-label housing, printing and packaging.
How does Triac compare with DALI or 0–10V dimming?
Triac dims directly from the mains with no control wiring — the simplest and most economical option for local, per-room control. DALI and 0–10V suit projects needing addressable fixtures, group and scene control, and centralized building management.
