Technical Specs & Certifications
The PWM LED controller offered by Beauty (STC) Manufacturing Co., Ltd. is engineered for precision dimming and high-efficiency performance in modern LED lighting systems. At its core, the controller utilizes Pulse Width Modulation (PWM) technology to deliver smooth, flicker-free dimming by rapidly switching the current to the LEDs on and off at varying duty cycles. This method ensures stable light output across dimming ranges while maintaining consistent color temperature and minimizing thermal stress on the LED components.
In terms of system efficiency, when paired with high-performance LEDs, the overall lumens per watt (lm/W) output of lighting fixtures using our PWM controllers typically exceeds 120 lm/W, with top-tier configurations reaching up to 140–150 lm/W depending on the LED package and thermal design. This high efficacy is achieved through optimized driver circuitry that minimizes power loss and supports constant current regulation, ensuring maximum energy conversion from electrical input to visible light.
Beauty STC places strong emphasis on light quality, and our PWM controllers are specifically designed to work seamlessly with LEDs that achieve a Color Rendering Index (CRI) greater than 90. This high CRI ensures accurate and vibrant color representation, making the lighting ideal for applications in retail, healthcare, studios, and premium residential environments where true color perception is critical. The controller maintains stable current delivery, preventing color shift even at low dimming levels, thereby preserving the high CRI performance across the entire dimming range.
Regarding environmental protection, the PWM LED controllers from Beauty STC are available in multiple configurations with IP ratings to suit diverse installation conditions. Standard indoor units are rated at IP20, providing basic protection against touch and dust ingress. For outdoor or harsh environments, we offer sealed driver-controller combinations with IP65, IP66, and IP67 ratings, ensuring full protection against dust, water jets, and temporary immersion. These ruggedized versions are commonly used in outdoor architectural lighting, parking structures, and industrial facilities.

Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, Guangdong Province, serves as a primary production hub for our LED lighting and control products. This modern factory is strategically located within a major industrial zone, benefiting from excellent infrastructure and a skilled regional workforce. The facility operates under stringent ISO 9001 quality management standards, with dedicated clean rooms for critical processes and comprehensive environmental controls to ensure consistent manufacturing conditions.
Our Surface Mount Technology (SMT) production lines form the backbone of electronic assembly at the Jiangmen site. We utilize multiple high-speed, precision Yamaha YS series machines, specifically the YSM20 and YSM10 models, configured in optimized lines. These machines handle components ranging from 0201 passives up to larger connectors and ICs with high placement accuracy (±25µm @ 3σ) and throughput exceeding 60,000 components per hour per line. The lines integrate automatic optical inspection (AOI) stations immediately post-reflow for comprehensive solder joint and component placement verification, ensuring defect detection before products proceed to subsequent stages. This capability supports both high-volume production runs and flexible small-batch manufacturing for specialized controllers.
Rigorous aging and reliability testing is a non-negotiable step for all our LED drivers and controllers, including PWM units. Completed PCB assemblies undergo a mandatory 48 to 72-hour burn-in process within our dedicated aging chamber area. Units operate at elevated temperatures (typically 65-75°C ambient) and under full rated load conditions. During this period, sophisticated monitoring systems continuously track critical parameters such as output voltage stability, current ripple, thermal performance of key components, and overall functional integrity. Any unit exhibiting parameter drift beyond tightly controlled thresholds is automatically flagged and removed from the production flow for root cause analysis. This extended stress testing significantly weeds out infant mortality failures before products reach customers.
