LED driver and dimmer are a type of transformer and electrical device which are used to regulate power to LED's, string lights, sign lights, and other electrically powered devices. LED drivers are available in a wide range of configurations and sizes to help accommodate today's all types of DIY projects and new fixture designs.
This LED Driver has a "120 Volts" Input Voltage which is converted to "27-42" Volts. (DC)
Measurements 3.35" Long x 1.5" Width x 1" Height.
This LED Driver is "dimmable" from (100% to 1%) without flickering.
Dimming is accomplished by reducing the amount of current going through it or by or by PWM. PWM is Pulse width modulation and uses a rectangular waveform and variable positive duty cycle to adjust the brightness or the LED proportionally.
Our LED Drivers are made with quality parts that are fully potted. Potting helps protect the internal components from being damaged in the event they are exposed to the elements.
Always make sure to check LED input requirements when setting up a new circuit using an LED Driver.
Always make sure power is off when working with electrical parts and fixtures.

FAQs
what is LED driver?
A LED driver regulates voltage and current to keep LEDs safe, steady, and efficient, with protections against overvoltage, short circuits, and overheating.
How does LED driver work?
A LED driver regulates current and voltage to keep LEDs safe, bright, and long-lasting.
How to connect LED driver?
To connect a LED driver, wire the input to the power source, output to the LED with correct polarity, ensure ratings match, and then power on.
How to check LED driver?
To check a LED driver, measure input power, test output voltage or current (with LED connected if needed), and replace if output is missing or unstable.
LED driver AC to DC
Constant Voltage – provides a fixed DC voltage (e.g., 12V or 24V) for LED strips.Constant Current – regulates current (e.g., 350mA, 700mA) for high-power LEDs.
How to connect LED driver to power supply?
To connect a LED driver, turn off power, wire input to the supply and output to the LED with correct polarity, then switch power back on.
LED light with driver
A LED light with a driver uses it to regulate power, converting AC to the correct DC; matching ratings and correct wiring ensures safe, efficient, long-lasting operation.
LED light without driver
Using a LED without a driver risks overheating or burnout; a driver ensures safe, efficient, and long-lasting operation.
