Frequently Asked Questions

Can I use the LDH-45A-500DA for a 500mA LED downlight with a higher-voltage LED string?

Yes, if the downlight is a constant current 500mA load and its total LED forward voltage stays within 24-86V. This model is better suited to higher-voltage strings than lower-voltage constant current loads because its regulated range starts at 24V. The connected load must also stay within 43W.

Is this driver a fit for outdoor signage modules that need 500mA constant current?

It can be a fit for constant current signage modules operating at 500mA with a total forward voltage in the 24-86V range. The IP67 rating and -40°C to +70°C operating temperature range support use in harsh environments. It should not be used where the LED product expects fixed-voltage output.

Can the LDH-45A-500DA power a compact LED array that needs a boosted output voltage?

Yes, this is a step-up constant current driver with 500mA output, up to 86V output voltage, and a 24-86V constant current range. It works for small LED arrays that need a higher LED string voltage while staying inside the 43W limit. It is intended for constant current loads, not fixed-voltage LED assemblies.

How should I verify LED compatibility with the LDH-45A-500DA?

Your LED load must require constant current at 500mA, and the total forward voltage of the LED string must fall within 24-86V. The number of LEDs depends on each LED's forward voltage, so compatibility is based on the summed forward voltage rather than a fixed LED quantity. The driver is rated for 43W maximum.

Is the LDH-45A-500DA suitable for wet and temperature-variable locations?

Yes, it carries an IP67 waterproof rating and operates from -40°C to +70°C. Those ratings make it appropriate for enclosed outdoor lighting systems and other locations where moisture and dust exposure are expected. The housing dimensions are 75.0 × 53.0 × 22.7 mm.
