Frequently Asked Questions
Can I use the LDH-25-250 for LED downlights that need a low constant current?
Yes, this driver is rated for 250 mA constant current output and is intended for LED loads that fall within its 12-84V constant current range. It is not a constant voltage driver, so it should be used with constant current downlight loads rather than constant voltage LED products.
Is the LDH-25-250 suitable for signage modules or small LED arrays?
It can suit signage modules or small LED arrays when the LEDs are designed for 250 mA constant current operation. The load must remain within the 12-84V constant current range, and the number of LEDs depends on the forward voltage of each LED.
Can this model be used when the input supply is lower than the LED load voltage?
Yes, the LDH-25-250 is a step-up constant current driver with a 9-32VAC input and up to 84V output. That makes it suitable for constant current LED loads where the required LED voltage is higher than the available input range.
How do I know if an LED load is compatible with the LDH-25-250?
The LED load must be designed for 250 mA constant current operation and must fall within the 12-84V constant current output range. The exact number of LEDs cannot be set from this driver alone because it depends on the forward voltage of each LED.
How does the LDH-25-250 compare with other LDH-25 models?
Within the LDH-25 family, the 250 and 250W models are 250 mA, 12-84V, 21W; the 350 and 350W models are 350 mA, 12-72V, 25.2W; the 500 and 500W models are 500 mA, 12-50V, 25W; and the 700 and 700W models are 700 mA, 12-36V, 25.2W. The non-W version is pin style, while the W version is wire style.
