Frequently Asked Questions
Can I use the LDDS-500HW for a 500mA LED downlight?
Yes, if the fixture is designed for 500mA constant current input. This driver is a constant current step-down model rated at 45W with a 45-2V output range, so it should be paired with a load that needs controlled current rather than fixed voltage.
Is the LDDS-500HW suitable for constant current signage modules?
It can be suitable for signage modules that are specified for 500mA constant current operation. It is not intended for constant voltage LED modules, because this model regulates current across a 45-2V range instead of providing a fixed voltage output.
Can this driver run a higher-current small LED array?
Yes, it is a better match for small LED arrays that need 500mA constant current rather than 350mA or 700mA. The 45W rating and step-down design make it appropriate when the source and LED load both stay within the unit's specified electrical range.
How many LEDs can the LDDS-500HW drive?
That depends on the forward voltage of each LED, because this driver operates over a 45-2V constant current range. There is no single LED count for the LDDS-500HW; the correct check is whether the LED string stays within that voltage window at 500mA constant current.
How does the LDDS-500HW compare with the other wire-style LDDS versions?
The series spans LDDS-250HW and LDDS-250HWB at 0.25mA, LDDS-300HW and LDDS-300HWB at 0.3mA, LDDS-350HW and LDDS-350HWB at 0.35mA, LDDS-500HWB matching this unit at 0.5mA, LDDS-700HW and LDDS-700HWB at 0.7mA, and LDDS-1000HW and LDDS-1000HWB at 1mA. All of them are listed at 45W with the same 45-2V constant current range.
