Frequently Asked Questions
Can I use the LDH-45A-700 for a 700mA LED downlight retrofit?
Yes, if the downlight is designed for constant current operation at 700mA. This model delivers 700mA across a 12-64V constant current range and supports up to 44.8W.
Is the LDH-45A-700 a good choice for signage lighting that uses constant current modules?
It can be, provided the signage module is a 700mA constant current load and not a constant voltage product. The driver is a step-up constant current unit with a 12-64V operating range and a 44.8W rating.
Can this driver run a compact high-output LED array?
Yes, small LED arrays that require 700mA constant current can be paired with this model when their total forward voltage falls within 12-64V. The available output power is 44.8W, so the array also needs to stay within that limit.
How do I know if my LEDs are compatible with this driver?
Match the LEDs by drive type first: this is a constant current driver, not a constant voltage power supply. It outputs 700mA over a 12-64V constant current range, and the number of LEDs depends on each LED forward voltage rather than a fixed LED count.
How does the LDH-45A-700 compare with the other 700mA LDH-45A versions?
LDH-45A-700 and LDH-45A-700W are 44.8W, 700mA models with a 12-64V constant current range, while LDH-45A-700DA and LDH-45A-700WDA are 44.8W, 700mA models with a 24-64V range. The standard and DA versions are pin style, while the W and WDA versions are wire style.
