Frequently Asked Questions
Can the LDH-45A-700WDA be used for 700mA LED downlights with a longer series string?
Yes, as long as the downlight is a constant current 700mA load and its total forward voltage stays within 24-64V. The driver is rated for 44.8W and is designed for step-up constant current operation.
Is this model suitable for constant current signage modules in outdoor signs?
It can be suitable when the signage modules are designed for 700mA constant current drive. The IP67 rating supports outdoor or damp locations, and the electrical load must stay within the 24-64V constant current range and 44.8W rating.
Can I use this driver for a compact LED array exposed to heat, cold, or moisture?
Yes, it is rated IP67 and has an operating temperature range of -40°C to +70°C. The LED array must still be a 700mA constant current load whose total forward voltage remains between 24V and 64V.
Will this work with my LED board, and does it support a fixed number of LEDs?
This driver outputs 700mA constant current across a 24-64V range, so compatibility depends on the board's required current and total forward voltage. The number of LEDs is not fixed because it depends on each LED's forward voltage, and this unit should not be treated like a constant voltage supply.
What environmental conditions is the LDH-45A-700WDA designed to handle?
The housing is rated IP67 waterproof, and the operating temperature range is -40°C to +70°C. Those ratings make it appropriate for demanding indoor or outdoor environments where water, dust, and temperature swings are factors.
