CC Non-dimmable LED driver

10 products

The CC non-dimmable LED driver is an LED power solution that centers on the principle of constant current, ensuring that the LED components receive a steady flow of electricity. 

This unwavering current supply is the hallmark of the CC driver, providing a reliable and consistent performance that is vital for maintaining the brightness and lifespan of LED lights. 

Despite not being equipped with dimming capabilities, the CC driver's commitment to a stable current output makes it an excellent choice for applications where a uniform lighting level is paramount. 

FAQ About CC Non-dimmable LED driver

Direct engineering answers on forward voltage matching, wiring limits, and constant current driver selection.

A CC non-dimmable LED driver delivers a fixed milliamp output while letting its DC voltage float across a set window to match the forward voltage of connected LEDs. Unlike standard power supplies that hold 12V or 24V steady, constant current drivers regulate amperage directly—commonly 150mA, 350mA, 700mA, or 1050mA. You use them to power bare LED downlights, COB spotlights, track heads, and custom puck fixtures that lack internal current-limiting resistors.

To size a CC non-dimmable LED driver, add the forward voltages of all series-connected LED modules together and verify the sum sits safely inside the driver's output DC voltage range. For example, our SN-15 series delivers a 9–42Vdc operating window at 15-watt maximum loads. If you run three COB downlights with a forward voltage of 9.2V each, your total load is 27.6V. Because 27.6V falls squarely between 9V and 42V, the driver regulates current cleanly without dropping out.

Fixtures connected to a constant current non-dimmable LED driver must be wired in series so every diode receives the exact same milliamp flow. If you wire constant current fixtures in parallel, current splits unevenly across parallel branches due to slight variations in diode forward voltage and thermal resistance. The branch with lower resistance draws excess current, overheats through thermal runaway, and burns out, quickly forcing all remaining current into the surviving fixtures.

NFC programming on an SN series CC non-dimmable LED driver lets you set precise output milliamps in 1mA increments using a handheld NFC tool or smartphone app without opening the casing. Models like the SN-45-300-1050-G1NF cover 300mA to 1050mA in a single housing. Instead of stocking separate drivers for 350mA, 500mA, 700mA, and 1050mA fixtures, an installer programs the exact target current wirelessly in two seconds on the bench, even when the driver is unpowered.
