Frequently Asked Questions
Can I use the LDH-45B-700W for a 700mA recessed LED downlight string?
Yes, this driver is meant for constant current LED operation at 700mA, which suits many recessed and architectural downlight strings. It provides a 21-64V constant current range and up to 44.8W, so the total forward voltage of the LEDs must stay within that range. It should not be used for constant voltage LED products.
Is the LDH-45B-700W suitable for constant current channel-letter or signage modules?
It can be suitable when the signage modules are designed for 700mA constant current drive. With a 21-64V output range and 44.8W maximum power, it fits many constant current module strings used in compact signage assemblies. It is not the correct choice for modules that expect a fixed constant voltage supply.
Can this driver be used for a small LED array in damp or outdoor locations?
Yes, the IP67 waterproof rating makes it appropriate for damp or outdoor environments when used inside a properly designed lighting system. It also supports operation from -40°C to +70°C, which is useful in exposed conditions. The LED array must still be a 700mA constant current load within the 21-64V range.
How do I verify LED compatibility with the LDH-45B-700W?
Start by confirming the LEDs require 700mA constant current rather than constant voltage. Then check that the combined LED forward voltage falls within the driver's 21-64V constant current range. The number of LEDs depends on each LED's forward voltage, so there is no fixed LED count.
Does the LDH-45B-700W handle harsh operating environments?
Yes, it is rated IP67 waterproof and has an operating temperature range of -40°C to +70°C. That makes it suitable for enclosed lighting systems exposed to dust, moisture, and wide ambient temperature swings. Its output remains 700mA constant current up to 44.8W.
