Frequently Asked Questions

Can I use the LDH-25-500W for a 500mA LED downlight system?

Yes, if the downlight requires constant current at 500mA and the total LED forward voltage stays within the 12-50V CC range. This model provides up to 25W and is designed for constant current LED loads rather than constant voltage lighting products.

Will the LDH-25-500W work with small LED arrays in compact lighting equipment?

It is intended for small LED arrays that need 500mA regulated current and up to 25W output. Its constant current range is 12-50V, and the compact body measures 52.4 × 27.2 × 24.0 mm.

Can this driver be used for constant current signage modules?

Yes, when the signage module is specified for 500mA constant current operation and the total LED forward voltage is within 12-50V. It should not be used as a substitute for a constant voltage power supply for signage modules that expect fixed-voltage input.

How should I size an LED load for the LDH-25-500W?

Match the LED load to 500mA constant current operation and keep the combined forward voltage within the 12-50V CC range. The number of LEDs will depend on the forward voltage of each LED, so sizing should be based on total forward voltage instead of a specific LED quantity.

What operating conditions is the LDH-25-500W rated for?

This driver is rated for -40°C to +70°C operation and is backed by a 3 year warranty. It also carries CE certification and lists efficiency up to 95%.
