Frequently Asked Questions
Can I use the LPF-40-20 with 20V LED strip or linear lighting?
Yes, if the lighting product is designed for 20V input and the total load stays within 40W. This unit delivers 20V output at up to 2A, so it should only be paired with 20V lighting products that fit inside that power limit.
Is the LPF-40-20 a good fit for 20V sign lighting?
It can be used for 20V sign lighting loads up to 40W. The IP67 Waterproof rating also makes it appropriate for signage installations where the power supply may face outdoor moisture.
Can this power supply run 20V outdoor architectural lighting?
It can support 20V outdoor architectural or accent lighting as long as the connected load is within 40W. Its IP67 enclosure and -40°C to +80°C operating range make the driver itself suitable for exposed conditions.
How much 20V LED strip can the LPF-40-20 support?
The length depends on the strip's rated power per meter. Use 40W divided by the strip's W/m to estimate the maximum length, then confirm the strip is a 20V product and that total demand stays at or below 40W.
Is the LPF-40-20 suitable for wet locations?
Yes, the driver carries an IP67 Waterproof rating, so it is intended for wet and outdoor environments. It is also rated to operate from -40°C to +80°C, which supports use in both cold and hot settings.
How does the LPF-40-20 compare with other LPF-40 voltage versions?
The fixed-output LPF-40 range includes 12V at 40.08W and 3.34A, 15V at 40.08W and 2.67A, 20V at 40W and 2A, 24V at 40.08W and 1.67A, 30V at 40.2W and 1.34A, 36V at 40.32W and 1.12A, 42V at 40.32W and 0.96A, 48V at 40.32W and 0.84A, and 54V at 41.04W and 0.76A. Selection is mainly about matching the required output voltage and current to the load.
