Magna-Power TSA-80-186/208+GPIB

The Magna-Power TSA-80-186/208+GPIB is a programmable DC power supply delivering 80V at 186A (14.88 kW) output for demanding laboratory, integration, and industrial test applications. Built on IGBT-based power processing topology, this 3U rack-mount unit accepts 208VAC 3-phase input (187–229 VAC operating range, 50/60 Hz) and provides independent voltage and current programming via GPIB (IEEE-488) and SCPI interfaces. The supply incorporates class-leading line and load regulation, inrush current limiting, and isolated 37-pin external I/O for analog programming and remote monitoring. All units include comprehensive diagnostics—phase loss, thermal fault detection, overvoltage/overcurrent trip, and fuse status—with latching fault memory. Remote analog programming supports slew rates of 90 Hz (voltage) and 60 Hz (current) with High Slew Rate Option availability. Output voltage and current are continuously monitored and available for readback. Designed and manufactured in the USA, the TSA-80-186/208+GPIB combines precision DC sourcing with flexible control architecture for ATE integration and unattended operation in demanding environments.
