Class II or Class 2??
It is easy to confuse these two ratings so let’s make sure we have the hang of it now that we are towards the end of understanding LED power supplies. A Class 2 power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the Standard UL 1310 requirements. Class 2 power supplies are limited to 60VDC and 100 Watts. Since their power is limited, Class 2 power supplies cannot power as many LEDs as others outside the rating. This is where you must determine if you want to run a longer length from one power supply, or stick with the safety of a Class 2 power supply which are protected from fire and electric shock.
A Class II rating actually just refers to the input and output wires being double insulated. Class II drivers are popular as they do not require a ground connection.
Dimmable LED Power Supplies
If your LEDs are dimmable and you would like to adjust their brightness, make sure you choose a power supply that has dimming capabilities. Power supply specifications should list whether a power source is dimmable or not and what dimmer control type it uses. I will go over the two control types briefly:
PWM Dimming: Also known as pulse-width modulation dimming, can be used on all power supplies. Even the power supplies on our site that don’t say ‘dimmable’ right in the specs can be dimmed through wall mounted or remote PWM dimmers. This is because PWM dimmers go in-line with the strip lights, dimming on the 12VDC side of the circuit. PWM dimmers actually pulse the lights at high frequencies to change the perception of light to the naked eye. The higher the frequency, the brighter they will be.
