Frequently Asked Questions
Can the LDDS-300HW be used for a 300mA LED downlight?
Yes, if the downlight is a constant-current design that requires 300mA and its LED load falls within the 45-2V CC range. Because this is a 45W constant-current driver, it is not the correct match for constant-voltage lighting products.
Is the LDDS-300HW suitable for architectural signage modules?
It can be used for constant-current signage modules that need 300mA and operate within the 45-2V output range. The IP67 rating is useful where moisture or dust protection matters.
Can I use this driver for a compact LED array in a small fixture?
Yes, provided the LED array is rated for constant-current 300mA operation and stays within the 45-2V CC range. The exact number of LEDs depends on the forward voltage of each LED rather than a preset count.
What LEDs are compatible with the LDDS-300HW?
Compatible loads are constant-current LEDs that need 300mA and fit inside the 45-2V output range. Constant-voltage strips are not compatible, and the LED count depends on the forward voltage of the LEDs being used.
How does the LDDS-300HW compare with other LDDS-HW and LDDS-HWB versions?
All listed siblings share the same 45W rating and 45-2V CC range. The difference is output current: 0.25mA on the 250 models, 0.3mA on the 300 models, 0.35mA on the 350 models, 0.5mA on the 500 models, 0.7mA on the 700 models, and 1mA on the 1000 models.
