FAQs
What is the primary function of a constant current LED driver?
A constant current LED driver's primary function is to supply a stable and consistent amount of electrical current to LEDs, which is essential for their optimal performance, lifespan, and consistent brightness.
Is this LED driver suitable for outdoor use?
No, this driver has an IP20 rating, which means it is protected against solid objects larger than 12.5mm but has no protection against water. It is only suitable for dry, indoor environments.
What is the maximum wattage this driver can support?
This driver is designed for LED loads between 12W and 18W, given the output voltage range of DC 36-63V and a constant output current of 250mA.
What types of LEDs can I power with this driver?
You can power LED modules or strips that require a constant current of 250mA and operate within a voltage range of DC 36-63V.
What do the built-in protections do?
The over-voltage, over-current, over-temperature, and short-circuit protections are safety features that prevent damage to the driver and the connected LED load in case of electrical faults or unstable power conditions.
Can I use this driver with a dimmer switch?
This driver is a constant current type and is not designed to be used with standard AC dimmers. Dimming would typically be achieved using PWM (Pulse Width Modulation) controllers compatible with the LED load and the driver's output.
Troubleshooting
LEDs do not light up
Verify AC input power is present. Check that the output polarity is correctly connected to the LED load. Ensure the LED load's voltage requirements are within the 36-63V DC range and its power requirement is within 12-18W for this driver.
LEDs flicker or dim intermittently
Check for loose wire connections at both the input and output terminals. Ensure the LED load is stable and not exceeding the driver's current or voltage limits. Test with a different LED load if possible.
Driver becomes excessively hot
Confirm the LED load wattage is within the 12-18W range and that the output voltage matches the LED requirements. Ensure the driver is adequately ventilated and not enclosed in a space with poor airflow. Check for short circuits in the LED wiring.
