120-277VAC CV 60W-300W Small Volume Switching Power Supply

Product Introduction

The SCPOWER Small Volume Switching Power Supply is a compact constant voltage AC-DC power supply designed to provide stable DC output for LED lighting applications. Supporting a wide 120–277VAC input range and multiple power options from 60W to 300W, it offers a compact and efficient solution for lighting systems where installation space is limited.

The series features a built-in active PFC circuit and delivers efficiency of up to 95%, helping improve energy efficiency and reduce power loss during operation. Its full aluminum housing provides effective protection and supports installation in dry and damp locations, while free-air convection cooling enables reliable operation without an external cooling fan.

As a non-dimmable power supply, the series is designed for LED lighting applications that require stable constant voltage output rather than dimming control. Built-in short-circuit, overload, and over-temperature protection, together with flicker-free output and a 5-year warranty, provides a reliable power solution for professional lighting projects.
