The Driver 21W 500mA Non-Dimmable is an independent constant-current driver with 21 W and 500 mA in a flat housing measuring 191 × 58 × 23 mm. It operates at 220–240 V AC with an input voltage range of 198–264 V AC and can also be run on 170–276 V DC. A power factor of at least 0.90 and total harmonic distortion (THD) of no more than 10 % at full load ensure grid-friendly operation. With IP20 and protection class II, it is intended for dry indoor spaces and is switched on/off.
