Frequently Asked Questions
Can the LDC-35DA be used for DALI-controlled LED downlights?
Yes, if the downlight is designed for constant current operation at 300mA and the LED load is within the 27-56V constant current range. This is a 35W constant current driver, so it is intended for LED loads that require regulated current rather than constant voltage.
Is the LDC-35DA suitable for signage modules in a DALI lighting system?
It can be, provided the signage module is a constant current LED load that operates at 300mA within 27-56V. It should not be treated like a constant voltage power supply, because this model is designed to regulate current to the LED load.
Can I use this driver for a small LED array in a DALI-based fixture?
Yes, if the array is designed for constant current drive at 300mA and its total forward voltage stays inside the 27-56V range. That makes it suitable for small LED arrays in fixtures that need a constant current driver instead of a constant voltage source.
How do I size an LED load for the LDC-35DA?
Match the LED load to 300mA constant current operation and keep the total forward voltage within the 27-56V CC output range. The number of LEDs depends on the forward voltage of each LED, so the correct match is based on current and combined forward voltage, not a specific LED count.
Is the LDC-35DA suitable for harsher ambient conditions?
This model has an operating temperature range of -25°C to +80°C, which gives it a wide ambient operating window. No IP rating is listed in the provided specs, so environmental suitability should be judged together with the enclosure and fixture design.
