100-277VAC CV 30W-150W High Power Factor Switching Power Supply

Product Introduction

The SCPOWER KV-ASL Series is a non-dimmable AC-DC switching power supply designed for reliable power conversion in LED lighting and other electronic applications. With a built-in active Power Factor Correction (PFC) circuit, it achieves a typical power factor of >0.9 at full load, helping improve power utilization and overall system efficiency.

Available with 12V, 24V, 36V, and 48VDC output options, the KV-ASL Series combines high efficiency, compact construction, and cost-effective performance. Efficiency reaches up to 92.5% at 230VAC/277VAC, depending on the model, reducing energy loss during operation.

The power supply features isolated input and output and integrated protection against short circuit, overload, and over-temperature conditions. With free-air convection cooling and an operating temperature range of -40°C to +40°C, it provides reliable operation without requiring an external cooling fan.

As a professional LED power supply manufacturer, SCPOWER provides the KV-ASL Series for lighting manufacturers, distributors, and system integrators seeking a dependable non-dimmable power solution for commercial, industrial, and general lighting applications.
