Frequently Asked Questions
Can I use the PLN-45-20 with a 20V LED strip or linear lighting system?
Yes, if the lighting load is designed for 20V operation and stays within 46W and 2.3A. The driver has a constant current voltage range of 15-20V, so the load's electrical requirements should match that output window.
Is the PLN-45-20 a good choice for 20V signage lighting?
It can be used for 20V signage applications that need no more than 46W total and 2.3A output current. The product features specifically state it is suitable for signage applications, and the IP64 housing adds protection for tougher locations.
Can this 20V driver handle compact commercial or display lighting loads?
Yes, for 20V lighting loads within 46W maximum output. Its wide 90-295VAC input range also makes it practical where the incoming mains supply may vary across sites.
How do I estimate the maximum 20V LED strip length for the PLN-45-20?
Use the driver's 46W maximum output as the limit. Maximum strip length = 46W divided by your strip's rated watts per meter, and you should also confirm the strip is rated for 20V and does not draw more than 2.3A; check your strip rated power per meter.
Is the PLN-45-20 suitable for damp or outdoor conditions?
Its IP64 rating means it is intended for dust exposure and splashing water rather than fully submerged or high-pressure washdown environments. The specified operating temperature range is -30°C to +50°C.
