Description

Product Introduction

 

 

The Eaglerise CS-15-300 SI is a specialized 12.6W constant current LED driver, engineered for manufacturers who prioritize both compact design and light quality. With a stabilized 300mA output, this driver is the go-to power solution for the next generation of LED spotlights, downlights, and circular ceiling panels.

 

In the 2024 Revision C update, Eaglerise has further optimized the thermal window and ripple control of the SI series. Its small Φ 42mm diameter allows for seamless integration into low-profile fixtures where internal space is at a premium. For B2B buyers, the CS-15-300 SI represents a reliable, "set-and-forget" component that meets stringent global standards for flicker-free lighting and energy efficiency.

Key Product Features

 

 

  • Precision Flicker-Free Performance: Specifically designed to eliminate stroboscopic effects, making it ideal for environments where high-quality visual comfort is required (offices, libraries, and retail).
  • Space-Efficient Circular Housing: The 42mm round footprint is purpose-built for integrated luminaire designs, fitting easily into standard spotlight housings and small junction boxes.
  • Advanced Protection Suite: Includes robust hardware protection for Short Circuit (SCP), Over Load (OLP), and Over Voltage (OVP) with automatic recovery.
  • High Efficiency & Power Factor: Delivers ≥ 82% efficiency at full load (230V), minimizing heat dissipation within the fixture and ensuring lower operational costs for end-users.
  • Global Safety Certification: Fully compliant with IEC61347, EN55015, and ErP2.0 EU 2019/2020, facilitating smooth international market entry for lamp manufacturers.

FAQ

Q: Can the CS-15-300 SI be used with high-power LED strips?

A: This driver is a constant current 300mA source. It is only suitable for LED strips or modules designed for constant current operation within the 27-42V window. It is not compatible with standard 12V/24V constant voltage strips.

Q: What is the benefit of the "Flicker-Free" rating (SVM ≤ 0.4)?

A: It ensures that the light output is stable enough for high-speed photography and reduces eye strain and headaches for people working under artificial light for extended periods.

Q: Is this driver dimmable?

A: No, the "SI" suffix indicates the standard fixed-output series. For Triac or DALI dimmable options in the same circular form factor, please contact our technical sales team.

Q: How does the "Auto-Resume" protection work?

A: If a short circuit or overload occurs, the driver temporarily shuts down to protect the LEDs. Once the wiring fault is corrected, it automatically resumes normal operation without requiring a manual reset.
