Constant Current Vs Constant Voltage Led Strip

If the circuit does not draw more that what is required it will work.

Constant current vs constant voltage led strip.

Constant current this type of driver will have a fixed current outp. Constant current led driver is generally used in industrial led lighting applications. The core components of led power supply include switching controller inductor switching component mosfet feedback resistor input filter device output filter device etc. Most common constant voltage drivers or power supplies are 12vdc or 24vdc.

Current controlled led tape lighting regulates light output across your run via ic s integrated circuits as compared to constant voltage which utilizes limiting resistors. Constant voltage this type of driver will have a fixed voltage output. The question of using a constant voltage or a constant current driver is usually one of the last to be answered. The current output for the driver will have a max rating.

This will depend on the led voltage rating. On the other hand constant current led drivers are manufactured to only operate constant current devices with specific ratings making them the more efficient of the two drivers. An led light that is rated for constant voltage usually specifies the amount of input voltage it needs to operate correctly. Switch to a different led strip solution if you want to use the different topology to enjoy the benefits of it.

It will be a fixed output. Constant voltage drivers are designed for a single direct current dc output voltage. The constant voltage led driver can provide constant voltage up to a certain current value. Constant voltage power supplies are used if leds need a different operating voltage than what s supplied by a power source.

Constant current drivers unlike constant voltage drivers don t make use of current limiters neither in the form of current limiting resistors nor current regulators which as a result allows for the direct connection to led s. Constant current led driver can output constant current in a certain voltage range. Let s start with identifying the differences. Constant current drivers are used to regulate the amount of current supplied to an led to maximize led lifetime.

Even though a constant voltage driver may be slightly less efficient it enables a full flexibility to allow a greater final load size. The constant current driver changes the voltage across the led allowing for a stable and constant current to the led. Below is a list of the major benefits of using the constant voltage and the constant current topologies.
