Frequently Asked Questions

Can I use the LDDS-350HWB with a dimmable LED downlight?

Yes, if the downlight is built for 350mA constant current operation. This model is a 350mA constant current step-down driver rated at 45W with a 45-2V output range, and the HWB version adds 3 in 1 dimmable capability.

Is the LDDS-350HWB a fit for dimmable signage LED modules?

It can be, provided the signage modules are specified for 350mA constant current rather than constant voltage. The driver delivers constant current across a 45-2V range and is rated IP67, which helps when the application needs a sealed driver body.

Can this model power a small dimmable LED array?

Yes, for small LED arrays that require 350mA constant current and fall within the 45-2V constant current range. Its 45W rating and compact 47.0 x 12.0 x 7.0 mm body make it suitable where both dimming and limited space matter.

How do I size the LDDS-350HWB to my LEDs?

Match it to LED loads that need 350mA constant current and whose combined forward voltage stays within 45-2V. The number of LEDs depends on each LED forward voltage, so compatibility is based on voltage range and current requirement, not a fixed LED quantity.

Can the LDDS-350HWB be used in harsh temperature or wet locations?

This driver is rated IP67 and has an operating temperature range of -40 degC to +55 degC. That makes it better suited to demanding environmental conditions than an indoor-only, non-sealed driver, as long as the rest of the system is specified accordingly.
