Power Line Communication
Ultra Compact
Full DC Dimming
CCT / Single Color
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-B can drive CCT or single
color LED, SDC25-E can drive single color only. For CCT application, please
connect LED’s common positive to pad “+”, cool white to pad “CW-”and warm
white to pad “WW-”. For single color application, please connect LED’s
positive to pad “+” and negative to pad “SINGLE-”.
Introduction
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
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
pad to master driver’s output.
Installation
Install steps
- Make sure the driver’s output current and voltage range match the LED light.
- Connect the output to LED light, make sure the polarity is correct and cable is well insulated.
- 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!
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!
Advanced features
Change rated output current
The output current can be set from the master driver via smart app, the
adjustable range of output current value is 100-700mA. Please refer to the
master driver’s instruction for detailed operation.
Output current trimming
Besides the output current setting, the output current also can be trimmed
from 100% to 50% of the rated current at 5% step. With this feature, the LED
current and light luminance can be matched preciously. Please refer to the
master driver’s instruction for detailed operation.
ON/OFF fade time adjust
The on/off fade time can be adjusted in range of 0- 25.5s from the master
driver. Please refer to the master driver’s instruction for detailed
operation.
Change dimming curve
The dimming curve can be changed from Logarithm, Linear and Optimized
logarithm. Please refer to the master driver’s instruction for detailed
operation.
Program the salve driver zone
The slave drivers connected to same master driver can be programmed to
different zones. User can adjust the brightness or color temperature of each
zone individually. Please refer to the master driver’s instruction for
detailed operation.
