15W CCT Adjustable LED Driver – Model WCL-S3A15-350
Reliable High-Current Constant Current LED Power Supply
The WellDriver WCL-S3A15-350 is a powerful 15W LED driver designed for indoor lighting applications requiring precise color temperature control. Equipped with a two-dip-switch configuration, it allows users to easily select from three correlated color temperatures (CCT) matched to the actual LED chip specifications. This driver delivers a stable 350mA constant current output and ensures flicker-free performance for enhanced visual comfort.
WCL-S3A15-350
CCT Adjustable Driver
3-CCT Selectable by Dip Switch
A two-position dip switch lets the installer set one of three correlated color temperatures (CCT) on site, matched to your actual LED chip specification — no controller, no app, no commissioning. Set the switch before or during installation and every luminaire on the project leaves the factory floor looking identical.
Switch 1 + 2
Three CCT Options
CCT values are defined by your LED board — typically warm / neutral / cool white.
350mA Constant
High-Current Output
Stable 350mA across 28–40V DC for high-output panels and downlights.
Flicker-Free
Eye Comfort Output
Consistent, stable illumination that minimises eye strain in offices and retail.
CCT Dip Switch vs 0–10V vs DALI — Which Should You Choose?
This model selects color temperature, not brightness. If your project needs dimming, choose a Triac, 0–10V or DALI driver instead.
| Feature | CCT Dip Switch (This Product) | 0–10V | DALI (DT8) |
|---|---|---|---|
| Function | Selects 3 preset CCTs | Dims brightness | Dims + tunes CCT digitally |
| Brightness Dimming | No — fixed output | Yes | Yes |
| Control Wire | None — set on the driver | 2 extra low-voltage wires | DALI bus |
| Commissioning | None required | None required | Addressing + commissioning |
| Installed Cost | Lowest | Medium | Highest |
| Best For | Panel lights, downlights, fixed-CCT projects | Commercial projects with analog control | Offices, malls, tunable-white BMS |

Why Choose WellDriver?
With extensive experience in LED driver manufacturing, WellDriver delivers innovative, safe, and efficient power solutions for the global market. All products are rigorously tested to comply with international safety and performance standards.
Dimensions & Installation
⚠️Installation notes: IP20 rated for indoor LED lighting only. Install in a ventilated position with clearance for heat dissipation; do not cover or seal the driver. Disconnect mains power before setting the dip switch. Wiring must be carried out by a qualified electrician. Match the 350mA constant current to your LED load and observe DC output polarity. For damp or outdoor locations, ask us about higher IP-rated options.

FAQ – 15W CCT Adjustable LED Driver WCL-S3A15-350
Does this driver dim the light?
No. The WCL-S3A15-350 is a CCT-selectable driver, not a dimmer — the dip switch changes color temperature between three presets while brightness stays fixed. For dimming, see our Triac, 0–10V or DALI drivers.
What are the three CCT values?
The three correlated color temperatures are matched to your actual LED chip specification — typically warm, neutral and cool white. Send us your LED board's CCT bins and we program the switch table before production.
Is 350mA the right current for my LED board?
Match the driver's 350mA constant current to your LED board's rated forward current, and confirm the board's forward voltage falls inside the 28–40V DC window (15W ÷ 350mA ≈ 40V). Send us your LED specification and we will confirm compatibility.
Can the input and output be customized?
Yes. Input voltage (220–240V AC) and output voltage (28–40V DC) are both listed as customizable, along with output current, CCT options, housing size and private-label printing.
Is the WCL-S3A15-350 suitable for outdoor use?
No. It is rated IP20 and specified for indoor LED lighting. For damp or outdoor locations, ask us about higher IP-rated options.
Do you offer OEM/ODM and private label service?
Yes. We support OEM & ODM customization for voltage, current, CCT values and size, including private-label housing, printing and packaging.
