Description

LCM-40TW Series is a 40W constant power output LED driver with two channels output for Tunable white function. It can operate from 180–277 V 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 -300C •50C case temperature under free air convection. LCM-40TW is designed based on DALI-2 D T 8 Tunable white function and is also usable as two independent output channels with D T 6 applications. LCM-40TW can be adjusted for light intensity and color temperature by a push button as a simple way dimming, so it provides the optimal design flexibility for LED Lighting luminaires.

NOTE

All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25C of ambient temperature.
De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
Efficiency is measured at 800mA50V output set by DIP switch
Current ripple is measured 500/0-1000/0 of maximum voltage under rated power delivery.
Standby power consumption is measured at 180-230VAC.
The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the
complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
The ambient temperature derating of 3.5C/1000m with fanless models and of 5C/1000m with fan models for operating altitude higher than 2000m(6500ft).
Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the start up time will be higher than 0.5 second.

DIMMING OPERATION

FIG 9 DIMMING OPERATION.JPG

※PUSH dimming (primary side)

The factory default dimming level is at 100%.
If 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 utilizing one common push button.
The maximum length of the cable from the push button to the last driver is 20 meters.
The additive push button can be connected only between the PUSH terminal, as displayed in the diagram, and AC/L (in brown or black); it will lead to short circuit if it is connected to AC/N.
