Magna Power SL140-42.5/440 DC Power Supply

Overview

The Magna Power SL140-42.5/440 is a programmable DC power supply delivering 140V at 42.5A for 6kW total output power. Part of the SL Series line, this unit employs a current-fed topology designed from the ground up for automated test equipment (ATE) system integrators. Built on nearly 40 years of Magna-Power innovation, it combines state-of-the-art semiconductors with advanced heat sink engineering to achieve industry-leading power density in a compact 1U (1.75" height) rack-mount form factor while maintaining ambient operating capability to 50°C.

Designed and manufactured in the USA, the SL140-42.5/440 offers extensive programmable protection features, comprehensive diagnostic functions, and flexible remote control options including SCPI API, RS232, and optional Ethernet/GPIB connectivity for integration into complex test systems.
