Magna-Power SL250-32/440 DC Power Supply

Overview

The Magna-Power SL250-32/440 is a programmable DC power supply designed for ATE (Automatic Test Equipment) system integration. Delivering 250VDC at 32A (8kW total output), it employs current-fed power processing topology built on nearly 40 years of Magna-Power innovation. The compact 1U (1.75" height) rack-mount form factor supports ambient operation up to 50°C, enabling installation in high-density equipment racks.

The unit features comprehensive remote programming via SCPI, with optional Ethernet and GPIB interfaces. Master-slave functionality allows parallel operation for higher power applications, while integrated AC contactor isolation ensures safe disconnect during standby or fault conditions.
