FAQ
Can I use the LDDS-1000HWB for a 1000mA LED downlight?
Yes, if the downlight is designed for constant current at 1000mA and its LED load stays within the 2-45V output range. This is a constant-current step-down driver, so it is not the right choice for a constant-voltage downlight.
Is the LDDS-1000HWB suitable for outdoor signage modules?
It can drive constant-current signage modules that need 1000mA and operate within the 2-45V output range. The datasheet lists -40°C to +55°C at full load and 20% to 90% RH non-condensing but no IP rating, so it is not specified for direct outdoor exposure.
Can this driver run a small high-power LED array?
Yes, it can power a small LED array if the array is a constant-current load rated for 1000mA and falls within the 2-45V output range. The exact number of LEDs depends on the forward voltage of each LED, not on a fixed LED count.
What kind of LED load is compatible with the LDDS-1000HWB?
This model is for constant-current LED loads, not constant-voltage LED strips or constant-voltage modules. It delivers 1000mA with a 2-45V constant-current output range, and the number of LEDs depends on the forward voltage of each LED in the load.
What is the difference between the LDDS-1000HWB and the other LDDS-HW/HWB models?
All listed siblings share the same 2-45V output range. The series current options are 250mA on LDDS-250HW and LDDS-250HWB, 300mA on LDDS-300HW and LDDS-300HWB, 350mA on LDDS-350HW and LDDS-350HWB, 500mA on LDDS-500HW and LDDS-500HWB, 700mA on LDDS-700HW and LDDS-700HWB, and 1000mA on LDDS-1000HW and LDDS-1000HWB; HW models use remote ON/OFF, HWB models add 3 in 1 dimming.
