Frequently Asked Questions
Can I use the LDH-45A-350 for a 350mA LED downlight string?
Yes, if the downlight string is designed for constant current operation at 350mA and its total forward voltage is within the 12-86V CC range. Because this is a constant current driver, it is intended for LED loads that require current regulation rather than constant voltage input.
Is the LDH-45A-350 suitable for long small-LED arrays with higher forward voltage?
It can be, because the constant current range extends up to 86V at 350mA. That makes it suitable for LED arrays where the total forward voltage is relatively high but still within the 12-86V range and 30.1W rating.
Can this model be used for slim signage or edge-lit fixtures that use constant current LEDs?
Yes, if those LEDs are driven at 350mA constant current and the complete load stays inside the 12-86V CC range. It is not intended for constant voltage signage products that expect a fixed-voltage supply.
How many LEDs can the LDH-45A-350 run?
That depends on the forward voltage of each LED, not a fixed LED count. The driver supplies 350mA constant current across a 12-86V range, so the full LED string must stay within that voltage window.
What are the main differences between the 350 output-current LDH models?
LDH-25-350 and LDH-25-350W are 25.2W models with a 12-72V CC range, while LDH-45A-350 and LDH-45A-350W are 30.1W with a 12-86V range and LDH-45A-350DA and LDH-45A-350WDA are 30.1W with a 24-86V range. LDH-45B-350 and LDH-45B-350W are 44.1W with a 21-126V CC range, LDH-45B-350DA and LDH-45B-350WDA are 44.1W with a 36-126V range, and the 1050, 500, 700, 1400, and 1750 versions use different output currents and voltage spans.
