Description

LCM-40TW Series is a 40W constant power output LED driver with two channels output for Tunable white function. It can operate from 180~277V AC and output current ranging between 500 mA to 1050 mA selectable by dip switch. Thanks to high efficiency up to 87%, it is able to operate for 30C~85C case temperature under free air convection. LCM-40TW is designed based on DALI-2 DT8 Tunable white and is also usable as two independent output channels with DT6 function. LCM-401TW can be adjusted for light intensity and color temperature by a push button as a simple way dimming, so it provides the design flexibility for LED Lighting application.

DIMMING OPERATION

Output wiring diagram

PUSH dimming (primary side)

• The factory default dimming level is at 100%.
• F the push action lasts less than 0.05 sec., it will not lead to a change for the status of the driver.
• Up to 10 drivers can perform the PUSH dimming at the same time when utlizing one common push button.
• The maximum length of the cable from the push button to the last driver is 20 meters.
  Action| Action duration
  ---|---
  Short Push| 0.1~1s
  Double Click| Click twice in 1.5s
  Long Push| 1.5~10s
