Instruction Manual

1. Power supply input
Connect to master driver’s 48Vdc output power, get
power and PLC commands from master. The power input
polarity is universal, and please connect each power lead
to master driver’s output with good insulation.
2. LED output
Connect to constant current driving LED lights. The
output voltage range is from 0 to 48Vdc and the rated
output current is from 100-700mA. The rated output
current is programmable from the master driver. Please
make sure the voltage and current match the luminaire.
The SDC25-BH can drive CCT or single color LED. For
CCT application, please connect black cable to LED’s
common positive pole, white cable to cool white and red
cable to warm white. For single color application, please
connect black cable to LED’s positive pole and connect
both white and red cable to negative pole.
The SDC25-EH is single color model, please connect
red cable to LED’s positive pole and black cable to
negative.

Introduction

Ultra Compact

3. Install steps
4 Automatic LED adaption
This driver verifies the LED character on each power
on. It will run a adaption process once the change of LED
is detected. During the adaption process, the lighting
fixture will dim up and down for about 10 seconds. After
this process, the driver will match the LED feature and
maintain a 0-100% full range physical non-flickering DC
dimming. Normally this adaption process happens on the
power on moment once LED is changed when the
brightness is higher than 30%.
For CCT application, each LED channel must has
same voltage and current feature for proper adaption and
working.
CAUTION: The adaption process CAN NOT detect the
value of LED rated current, so the rated current MUST be
set correctly from the master driver before connecting to
lighting fixture. Otherwise the lighting fixture can be
permanently damaged!
CCT / Single Color
This product is a slave LED driver to work with
specific master driver for LED lighting application. The
power input is DC 48V with power line communication
(PLC) commands and it can drive LED lights in voltage
range of 0-48V and rated current range of 100-700mA.
Besides dimming and color temperature adjusting,
the output current, fade time, current trim level, dimming
curve and group features are adjustable via the PLC
commands from master driver.
With the advanced full DC dimming scheme, the
connected luminaire will be flicker free from zero to
maximum brightness, and build premium lighting
experience.
Function & Size
1. Make sure the driver’s output current and voltage
range match the LED light.
2. Connect the output to LED light, make sure the
polarity is correct and cable is well insulated.
3. Connect the input to master driver’s output, make
sure the cable is well insulated.
CAUTION:
Do not connect ANY cable to AC power!
Only connect the input to compatible master driver!
