| Fitted control function |
Built-in 3-in-1 dimming with dim-to-off. |
| NFC app and device |
Use an NFC-capable phone and the MEAN WELL app. The catalog specifies Android 4.1 or iOS 12 updates. Locate the phone antenna and driver NFC sensing mark. |
| NFC programming sequence |
Turn off the driver input supply. Enable phone NFC; open MEAN WELL → Installation Manual/APP → PowerNFC, approach the sensing position and read the model and settings. Enter the required output current, tap Write, bring the phone antenna close to the sensing mark, and confirm the app displays Success. The interface also provides Read, Default and password controls. |
| 3-in-1 control inputs |
Apply 0–10 VDC, a 10 V PWM signal at 300 Hz–3 kHz, or 0–100 kΩ resistance between DIM+ and DIM−. Typical dimming-source current: 100 μA. |
| Dimming floor and off |
Minimum dimming is about 8%; output current is undefined between 0% and 8%. Output can fall to 0% at approximately 0 VDC, 0 kΩ, or 0% duty of the 10 V PWM control signal. |
| Synchronized resistance control |
The chart scales full-level resistance as 100 kΩ / N, where N is the number of drivers under synchronized dimming. |
| Control wiring restriction |
Do not connect DIM− to the negative LED output (−V). Direct connection to compatible LEDs is suggested; do not cascade an additional LED driver. |
| Dimming-off standby |
<0.5 W, measured at 230 VAC with dimming off; standard B/DA2 version. |
| NFC commissioning |
Use an NFC-enabled phone or tablet and the MEAN WELL app (Power NFC). Read and write parameters only with AC power off; otherwise internal magnetic interference can prevent normal current setting. |
| NFC reading and verification |
Keep the phone antenna less than 5 cm from the NFC tag. Read the current, edit the setting, then hold the antenna near the tag and select Setting. After Success, read the driver again to confirm that the intended current was saved. |
| NFC password |
The factory default has no password. A user password may contain up to 8 case-sensitive English letters or digits, with no special characters, and must be entered for subsequent writes. The password cannot be reset externally; retain it safely. Default restores the output current to its factory value. |
