Product Details

High quality PE294R 42V max 200ma constant current triac dimming led driver is one of the constont current dimming LED diver developed by China manufacturer Starwell with high power factor, high eficiency, highprecision, the use of the efficient stoble low loss switch control chip ond the high performance components mokes it with lownoiselong life and other characteristics.

High-Performance Constant Current Dimming LED Driver stands out as a flagship constant current dimming LED driver independently developed by our company, engineered to redefine reliability and efficiency in LED lighting applications. At its core, the driver boasts three key performance pillars: high power factor (PF), top-tier efficiency, and exceptional current precision—all of which address the critical demands of modern lighting systems, from commercial spaces to industrial facilities.

What sets PE294R apart is its meticulous component selection and circuit design. We adopt an efficient, stable, and low-loss switch control chip as the driver’s "brain," ensuring rapid, accurate response to dimming signals while minimizing energy waste during power conversion. Paired with high-performance electronic components—including low-resistance MOSFETs and precision current-sensing resistors—this design not only pushes the driver’s efficiency to industry-leading levels but also eliminates unnecessary heat generation, a common culprit behind shortened LED lifespans.

Beyond performance, PE294R prioritizes user experience and durability. Its low-noise operation is a standout feature: the optimized circuit layout and noise-suppression components prevent electromagnetic interference (EMI), ensuring the driver works quietly without disrupting nearby electronic devices—ideal for noise-sensitive environments like offices, hospitals, or residential areas. Additionally, the use of high-quality, temperature-resistant materials enhances its long-term stability, even in harsh operating conditions (such as high humidity or fluctuating temperatures), extending the driver’s service life to match the longevity of LED light sources themselves.

Whether for smart lighting systems requiring smooth dimming transitions or large-scale lighting projects demanding consistent performance, PE294R delivers a reliable, efficient solution that balances technical excellence with practical usability.
