Constant Current vs Constant Voltage vs DALI LED Driver
Match the driver type to how the LED module is built and whether you need control.
| Output | Fixed current | Fixed voltage | Addressable CC/CV |
|---|---|---|---|
| Load | LED boards | LED strips | LED boards/strips |
| Dimming | PWM/0-10V | 0-10V | DALI scenes |
| Best for | Fixtures | Strip runs | Smart buildings |
Use constant current for fixed boards, constant voltage for strips, and DALI when you need addressed smart control.
Frequently Asked Questions
Constant current or constant voltage?
Constant current for LED boards with a set forward voltage; constant voltage for strips and bars run in parallel.
What IP rating for outdoor drivers?
IP67 sealed drivers survive rain and dust; use them for street, area and facade lighting.
Can I dim a DALI driver with 0-10V?
No. DALI uses digital commands; pick a 0-10V driver if your system is analog.
Does XGW make IEC/CE drivers?
Yes. XGW LED drivers carry UL, CE, CB and DALI-2 certification for major markets.
