PSU HD48-3A+ 48V 3A 144W Linear Chassis Mount Power Supply

The PSU HD48-3A+ is a premium 48V 3A linear power supply designed to deliver clean, stable, and regulated DC power for commercial, industrial, laboratory, and telecommunications applications. With a continuous output of 48VDC at 3A and a total power rating of 144W, this chassis-mounted power supply is ideal for powering sensitive equipment that requires low-noise, highly stable voltage.

Featuring a universal input voltage of 100-240VAC, the PSU HD48-3A+ can be used worldwide without manual voltage selection. The adjustable output allows precise voltage calibration to meet application-specific requirements, while the remote sense function compensates for voltage drops across long cable runs, ensuring accurate voltage regulation directly at the load.

The robust chassis-mount construction makes this power supply suitable for permanent installation in industrial machinery, telecommunications systems, automation equipment, test benches, and OEM products. Operating over a temperature range of 0 C to +70 C (with derating), it provides dependable long-term performance. Certified to CE, cURus, and TUV safety standards, the PSU HD48-3A+ offers reliable and safe operation in demanding environments.
