Frequently Asked Questions
Can I use the LDH-45A-500WDA for LED downlights that need 500mA constant current?
Yes, this driver is built for constant current LED loads at 500mA and can regulate across a 24-86V constant current output range. That makes it suitable for LED downlights designed for a 500mA driver, as long as the total LED forward voltage stays within that range and the load stays within 43W.
Is this driver suitable for signage modules or custom channel letters?
It can be a fit for signage modules when the LED assembly is a constant current 500mA load rather than a constant voltage module. The driver is step-up, rated at 43W, and works across a 24-86V constant current range, so compatibility depends on the module's forward voltage requirements.
Can this power a small LED array in an enclosed or outdoor location?
Yes, the IP67 rating supports wet or dusty environments, and the operating temperature range is -40°C to +70°C. It is intended for constant current LED arrays at 500mA, with output regulated within 24-86V and up to 43W.
Will this work with my LED board, and how many LEDs can it run?
This is a constant current driver with a 24-86V output range at 500mA, so it should be matched to LED boards designed for 500mA constant current operation. The number of LEDs depends on each LED's forward voltage, so the total forward voltage of the array must remain within 24-86V rather than being judged by LED count alone.
What is the difference between the LDH-45A 500mA versions?
Within the 500mA LDH-45A group, LDH-45A-500 and LDH-45A-500W are 43W models with a 12-86V constant current range, while LDH-45A-500DA and LDH-45A-500WDA are 43W models with a 24-86V constant current range. The W versions are wire style, and the non-W versions are pin style.
