Overview
The Pickering 60-191 family is a high-current LXI switching and sense platform designed to sit between multiple high-current power supply units and a device or system under test. Each unit can programmatically connect or disconnect each PSU's positive and negative outputs together with their associated high- and low-sense lines.
Rather than hand-building a contactor-and-digital-output assembly, engineers get a fully tested, maintainable LXI instrument in a standard 4U enclosure. A built-in sequencing service stores up to 5,000 predefined switching sequences executable from software or hardware triggers, reducing host transactions and system latency.
Key Benefits
80 A / 300 V switching in a standard 4U LXI box replaces custom contactor assemblies; onboard 5,000-sequence storage cuts host traffic and latency; integrated 1 A sense relays keep power and sense switching in one instrument.
Applications
EV battery and high-drain automotive electronics test; fuel-cell and hydrogen-electrolysis research; solar inverter and energy-storage test; aerospace development; functional/production testing of high-current power supplies.
