Overview

SE-20-50-100-W5D is the 9-42Vdc output model of this series: typical efficiency 85%(at full load).

Features

  • Ultra-small, thin and light screwless end cap.
  • The housing is made from V0 flame retardant PC materials from SAMSUNG/COVESTRO.
  • Eight DT6/DT8 device types are integrated in one device, configurable via NFC Lighting APP. RGBCW, W, 2×CT (sync), and XY are single - address; 2×CT (async), XY+CT, RGB+CT, and XY+W are double - address.
  • Change the output current, fade time and other parameters on the NFC programmer or via the App, and sync the parameters to the driver.
  • The current gear step value can be set as low as 1mA, offering higher compatibility and finer precision.
  • Soft-on and fade-in dimming function enhances your visual comfort.
  • T-PWM Super depth dimming technology, dimming depth can reach 0.1%
  • 0-100% full dimming without video flash, high frequency exemption assessment level
  • Comply with the EU’s ErP Directive, networked standby<0.5W.
  • When there is no load, the output will be 0V to prevent damage to LEDs due to poor contact.
  • Overheat, over voltage, overload, short circuit protection and automatic recovery.
  • Suitable for ClassⅠ/Ⅱ/Ⅲ indoor light fixtures.
  • Normal service life can reach 100,000 hours.
  • 5-year warranty (Rubycon capacitor)
