Frequently Asked Questions
Can I use the LDC-55 for higher-power LED downlights?
Yes, if the downlight is designed for constant current operation at 500mA and the LED load falls within the 27-56V constant current range. With 55W output, it sits above the 35W models in the same family while still using constant current operation rather than constant voltage output.
Is the LDC-55 a fit for larger signage modules or LED light boxes?
It can be a fit for signage modules designed as a constant current LED load at 500mA within 27-56V. This driver is not for constant voltage signage systems, so the module should be specified for constant current operation.
Can the LDC-55 run a small LED array with more power than a 35W driver?
Yes, if the array is built for 500mA constant current operation and its total forward voltage is within 27-56V. The 55W rating gives more output capacity than the 35W versions, but the load still has to match the current and voltage window of this driver.
What LED load is compatible with the LDC-55?
The compatible load is a constant current LED assembly rated for 500mA with a total forward voltage in the 27-56V CC range. The number of LEDs depends on each LED's forward voltage, so the correct match is determined by the load's total forward voltage rather than a fixed LED count.
How does the LDC-55 compare to other LDC linear series options?
LDC-55 is a 55W, 500mA model with a 27-56V CC range. In the same family, LDC-35, LDC-35B, and LDC-35DA are 35W at 300mA, LDC-35DA2 is 35W at 700mA, LDC-55B and LDC-55DA match 55W and 500mA, LDC-55DA2 is 55W at 1050mA, LDC-80, LDC-80B, and LDC-80DA are 80W at 700mA, and LDC-80DA2 is 80W at 1400mA, all with a 27-56V CC range; the family list also includes LDC-55B-33K OHM and LDC-80B 68K Ohm variants.
