Frequently Asked Questions
Can the LDH-45B-700DA power a 700mA LED downlight assembly?
Yes, if the downlight assembly is a constant current load rated for 700mA. This model operates over a 36-64V constant current output range with up to 44.8W, so it fits LED strings whose combined forward voltage is within that range. It is not designed for constant voltage lighting products.
Is this a good option for 700mA signage modules with a higher forward voltage?
Yes, this version is better suited to higher-forward-voltage 700mA module strings because its constant current range starts at 36V and extends to 64V. That makes it a fit for constant current signage modules in that window, up to 44.8W. It is not a substitute for a constant voltage driver.
Can I use the LDH-45B-700DA in outdoor LED equipment?
Yes, its IP67 waterproof rating supports outdoor or washdown-prone applications when the rest of the system is designed for the same environment. It also carries a -40°C to +70°C operating temperature range for demanding conditions. The LED load still must be a 700mA constant current load within 36-64V.
How many LEDs can the LDH-45B-700DA run?
There is no single LED count because the limit depends on each LED's forward voltage. Electrically, the driver supplies 700mA constant current and supports a total LED forward voltage of 36-64V. That means compatibility should be checked against the full string voltage, not by counting LEDs alone.
What environmental conditions is the LDH-45B-700DA built for?
This model is rated IP67 waterproof and operates from -40°C to +70°C, so it is designed for tough indoor or outdoor service conditions. Its compact size of 75.0 × 53.0 × 22.7 mm also helps where enclosure space is limited. Those environmental specs do not change the need for a 700mA constant current LED load.
