LDH-25-500

Yes, if the downlight is designed for constant current operation at 500mA and its total LED forward voltage falls within the 12-50V constant current range. This model is a 25W step-up constant current driver, so it is intended for LED loads that need regulated current rather than a fixed constant voltage output.

It can be suitable for signage modules only when the modules are built for 500mA constant current operation and the LED load stays within the 12-50V CC range. It is not the right choice for constant voltage signage products that expect a fixed voltage supply instead of a constant current driver.

Yes, this is a step-up DC/DC constant current driver with a 9-32VAC input and a 12-50V constant current output range. It is intended for small LED arrays that require 500mA regulated current and up to 25W output.

Your LED load needs to be a constant current load rated for 500mA, and its combined forward voltage must fall within the 12-50V CC output range. The exact number of LEDs depends on the forward voltage of each LED, so compatibility should be checked by total LED forward voltage rather than by a fixed LED count.

It is rated for operation from -40°C to +70°C, which supports use in equipment exposed to wide ambient temperature swings. That temperature range should still be evaluated together with the conditions inside the finished product.
