LED drivers are crucial components in LED lighting systems, and CEN-75-20 is one of them. This type of LED driver is based on a constant current source and topology that ensures excellent power factor with low total harmonic distortion (THD). Here we\'ll talk about its application field, and discuss its working principle.

CEN-75-20 operates with 90V-265Vac ±10%, so it can be used in most international environments. Being classified as Class II facility, this LED driver can be applied to many applications such as commercial down light, wall light, track light, and troffer luminaire.

This LED driver also comes with excellent protection functions, such as over voltage protection (OVP), overload protection (OPP), over temperature protection (OTP), and short circuit protection (SCP). It also has an isolation of up to 3750 VDC, suitable for many damp/wet/dry environments.

CEN-75-20 has a high efficiency and low total harmonic distortion (THD). Compared to other LED drivers, it utilizes an innovative constant current source for driving LED lighting. The device works by regulating a constant output current and establishing a 120° phase differential between the primary and secondary windings of the transformer.

The working principle of this LED driver is based on a controller chip and a power switch. The power switch is responsible for regulating the output current according to the commands from the controller chip which maintains the output constant. Thus, it ensures excellent power factor with low THD at all output levels.

CEN-75-20 also has a soft-start function, which provides a weak current to the LED. This helps to reduce light flicker and extends the lifespan of the lighting system. When the dimmer turns off, the power is totally cut-off to ensure the LEDs have a long lifespan.

CEN-75-20 is an ideal LED driver for many applications. Its constant current source topology and protection functions makes it suitable for different environments, and its innovative design ensures excellent power factor and low THD. With its soft-start function, CEN-75-20 is ideal for getting maximum performance from LED lighting.
