Frequently Asked Questions
Can I use the LDH-25-350W for a 350 mA LED downlight load?
Yes, this driver is designed for 350 mA constant current output and supports LED loads within a 12-72V constant current range. It is intended for constant current lighting loads, not constant voltage LED products.
Is the LDH-25-350W a fit for small LED arrays or channel-letter style LED modules?
It can be a fit when the LED load is specified for 350 mA constant current operation. The usable LED string voltage must stay within 12-72V, and the exact number of LEDs depends on the forward voltage of each LED.
Can this step-up driver be used where the LED string voltage is above the source voltage?
Yes, the LDH-25-350W accepts 9-32VAC input and can provide constant current output up to 72V. That makes it relevant for constant current LED systems where the required LED voltage is higher than the input supply range.
What should I verify before pairing LEDs with the LDH-25-350W?
Verify that the LEDs are intended for 350 mA constant current drive and that the full load operates inside the 12-72V constant current range. The driver does not define a fixed LED count because that depends on each LED's forward voltage.
Can the LDH-25-350W handle wide ambient temperature swings?
Its specified operating temperature range is -40°C to +70°C. No IP rating is listed in the provided specs, so moisture and enclosure protection need to be addressed separately from the driver's temperature rating.
