Introduction
This product is a 20W programmable constant current LED driver. Model
HDN20CB-E is for single color and HDN20CB-B can be used for CCT or single
color. It is Casaba ready and all features are programmable.
The output channel, rated current, fading time and trim level features are all
adjustable from the Casaba app. These features allow customer to apply in
various application with multiple options.
The advanced full DC dimming scheme is implemented, and it’s 100% physically
flicker free in whole dimming range. It also has very good low brightness
performance, to build elegant low brightness environment and on/off dimming
experience.
Setting output current and channel
The rated output current of HDN20CB is from 200mA to 1050mA, it needs to be
set from the Casaba app. To set the current and output mode, please make sure
the driver is unpaired and powered on. On the Casaba app, click on the driver
icon and select ‘Change profile’ option on the pop up manual (Fig.1). The
rated current and working mode can be selected in the list (Fig.2).
The HDN20CB-B model can be configured as CCT or single color model, once be
configured as single color model, user can connect lighting fixture to both
warm white and cool white channel.
The max output voltage
varies with the rated output current. The following table lists the max output
voltage and power with different current setting.
| Rated current | 200mA | 250mA | 300mA | 350mA | 400mA | 500mA | 600mA |
|---|---|---|---|---|---|---|---|
| Max output Volt. | 50V | 50V | 50V | 50V | 50V | 40V | 33.3V |
| Max output power | 1 OW | 12.5W | 15W | 17.5W | 20W | 20W | 20W |
| Rated current | 700mA | 800mA | 900mA | 1050mA | |||
| --- | --- | --- | --- | --- | |||
| Max output Volt. | 28.6V | 25V | 22.2V | 19V | |||
| Max output power | 20W | 20W | 20W | 20W |
Automatic LED adaption
This driver verifies the load character on each power on. It will run a load
adaption process once the change of load 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 the lighting fixture is changed with the
brightness is higher than 30%.
For HDN20CB-B, each LED channel must has same voltage and current feature for
proper adaption and working. If two channel’s voltage and current does not
match, the CCT adaption will fail and the driver will only work in single
color mode with limited function.
CAUTION: The adaption process CAN NOT detect the value of LED rated current,
so the driver rated current MUST be set correctly before connecting the driver
to the lighting fixture. Otherwise the lighting fixture may be permanently
damaged.
Advanced feature – Current trimming
To fine tune the LED driving current, please pair the driver first and double click on the driver icon to open the setting page. On the setting page please click on the ‘Current trim’ item in the PARAMETERS section (Fig.3). The output current can be trimmed from 100% to 50% of the rated current at 5% step (Fig.4).
Advanced feature – Change dimming curve
The dimming curve defines the trend of light output strength versus brightness
level (0-100%) showing on the app. Please pair the driver first and open the
setting page on the app, from the PARAMETERS section, the Dimming curve can be
changed from Logarithm, Linear and Optimized logarithm (Fig.5).
The Linear curve will result even light output power versus the brightness
level set on app, but for human eye sensing, the light output change is
relative too small at high brightness level.
The Logarithm curve will result strong brightness change at high brightness
level and this will make the brightness adjustment is more visible and logical
for human eye.
The Optimized logarithm curve is between linear and logarithm, results an
balanced brightness adjustment effect.
Advanced feature – ON/OFF fade time adjust
The on/off fade time can be adjusted on the setting page. Please pair the driver first and open the setting page on the app, from the PARAMETERS section, the ON/OFF fade time can be adjusted from 0-25.5 seconds. User can adjust it by entering value between 0-255 with the step of 0.1 seconds (Fig.6).
