Frequently Asked Questions
Can I use the LDDS-350HW for a constant current LED downlight?
Yes, if the downlight is designed for a 350mA constant current driver. This model is a constant current step-down driver rated at 45W with a 45-2V constant current output range, so the LED load needs to stay within that range rather than requiring a constant voltage supply.
Is the LDDS-350HW suitable for signage LED modules?
It can be suitable for signage modules only when the modules are built for 350mA constant current operation. The driver provides up to 45W and a 45-2V constant current range, so it is not the right choice for constant voltage signage products that expect a fixed voltage output.
Can this driver run a small LED array in a compact fixture?
Yes, this driver is often a fit for small LED arrays that need 350mA constant current and stay within the 45-2V output range. Its 47.0 x 12.0 x 7.0 mm size and wire-style format also make it easier to use where space is limited.
How do I know if the LDDS-350HW is compatible with my LED load?
Check that your LEDs require 350mA constant current and that the total LED forward voltage falls within the 45-2V constant current range. The number of LEDs depends on each LED's forward voltage, so there is no fixed LED count for this model.
What is the difference between the LDDS-350HW and other LDDS wire-type models?
In this series, the LDDS-250HW and LDDS-250HWB are 0.25mA, the LDDS-300HW and LDDS-300HWB are 0.3mA, the LDDS-350HWB matches this model at 0.35mA, the LDDS-500HW and LDDS-500HWB are 0.5mA, the LDDS-700HW and LDDS-700HWB are 0.7mA, and the LDDS-1000HW and LDDS-1000HWB are 1mA. All listed siblings share 45W power and the same 45-2V constant current range.
