Product Description

The SK-4000-48 Power Supply, a key member of the SK Series Power Module, is a high-efficiency 48V DC Converter designed for industrial applications such as telecommunications, data centers, and automation systems. It accepts a wide input voltage range of 85-305V AC/DC and delivers a stable 48V DC output with 4000W capacity, supporting direct parallel connection of up to 4 modules for scalable power solutions. Integrated with RS485 and CAN communication interfaces, it enables real-time monitoring and control in smart grid environments. Operating reliably between -40°C to +75°C, this rugged unit features overload/short-circuit protection and a 2.4-inch status display. While compact in design (3U height), its maintenance-free operation is offset by limited native battery support, typically requiring external backup systems for critical applications. The module excels in energy conversion efficiency (up to 96%) and supports remote firmware updates for adaptive industrial deployments.
