Introduction
This LED driver is designed to drive single color to RGB+White constant voltage LED products at DC18-25V (24V as default). With advanced circuit design, GaN and SiC components, it has excellent performance in a compact footprint.
The output function can be changed by profile option via Casambi app, user can also fine tune the output voltage to match the lighting fixture, change the PWM frequency and adjust the fading speed via the Casambi app.
There’s push button function on the driver, user can connect a normally open push switch to control the light. The control function can be defined to control brightness, scenes or groups via the Casambi app.
Dimension & layout
Select output function
The output function can be selected from single color, tunable white, RGB, RGBW and 4-ch dimmer options via the Casambi app.
To change the function, please power on the unit and make sure the unit is unpaired and then tap the ‘Change profile’ option via Casambi app and then select desired profile.
Output channel map
The output terminal will be mapped to specific function with different profile setting. Please refer to the following diagram of the output terminal mapping for RGBW, RGB, tunable white, single color and 4-ch dimmer application.
- Advanced feature – Change PWM frequency
The output PWM frequency can be adjusted from 500Hz to 20.4KHz with several options. Please open the setting page of the paired driver on the Casambi app and tap ‘PWM frequency’ in the ‘PARAMETERS’ section. (Fig.1-2)
This feature is used to resolve flicker or audible noise issues in certain applications. The efficiency of the driver decreases as the frequency increase and may generate excessive heat and cause protection. To ensure more stable working, please do not set to higher frequency if no noise or flicker issues occurred. - Advanced feature – Change fading speed
The color/brightness fading speed can be adjusted on the app. Please open the setting page of the paired driver on the Casambi app and tap ‘Fading speed’ in the ‘PARAMETERS’ section. (Fig.1-3). The fading speed can be adjusted from ‘direct’ to ‘very slow’ in 7 options. - Advanced feature – Trim output voltage
The output voltage can be adjusted from 75% to 105% of rated value in 1% steps. For rated voltage of 24V, the output voltage can be adjusted from 18V to 25.2V.
With this feature, user would be able to adjust the total power consumption, compensate the brightness fade for linear light at far end, or adjust the color hue of mixed RGB or RGBW application.
To fine tune the output voltage, please open the setting page of the paired driver on the Casambi app and tap ‘Voltage trim’ in the ‘PARAMETERS’ section (Fig.1-4), then input the percentage value of rated voltage.
