Frequently Asked Questions

Can the PWM-40-36 be used outdoors or in wet locations?

Yes. The PWM-40-36 is rated IP67, providing complete protection against dust ingress and resistance to temporary water immersion. Combined with its -40°C to +85°C operating temperature, it is suitable for outdoor enclosures, covered soffits, and wet-rated fixture installations.

How much 36V LED strip can I run from the PWM-40-36?

The PWM-40-36 delivers up to 40W at 36V. To estimate maximum strip length, divide 40W by your strip's rated watts per meter — for instance, a 10W/m strip supports roughly 4 meters. Confirm the actual rated power per meter of your specific strip before planning the run.

Is the PWM-40-36 suitable for dimmable 36V LED signage or channel letters?

Yes. The 3-in-1 dimming capability supports 0–10V, PWM, and resistance control methods, making the PWM-40-36 appropriate for dimmable 36V LED channel letters and backlit signage where brightness adjustment is required.

Can the PWM-40-36 power 36V LED strip in a cove or indirect lighting application?

Yes. Its constant voltage output at 36V and smooth PWM dimming output make the PWM-40-36 well suited for cove lighting and indirect architectural lighting where consistent brightness and dimming performance are important. The IP67 rating also allows placement in damp ceiling plenums.

Is the PWM-40-36 appropriate for low-voltage outdoor pathway or landscape lighting at 36V?

Yes. The IP67 waterproof enclosure and operating range down to -40°C allow the PWM-40-36 to be deployed in outdoor landscape lighting applications. The 36V output helps reduce voltage drop over longer cable runs compared to 12V systems at the same wattage.

How does the PWM-40-36 compare to the other 40W variants in the PWM series?

All four 40W variants share the same 40W power rating and physical dimensions. The PWM-40-12 outputs 12V at 3.34A, the PWM-40-24 outputs 24V at 1.67A, the PWM-40-36 outputs 36V at 1.12A, and the PWM-40-48 outputs 48V at 0.84A. Select the voltage that matches your LED strip specification.
