Fault insertion channel can switch up to 2.5kVA

Pickering Interfaces Inc. has included the 40-199 as the newest member of its 20 PXI fault insertion solutions. The module provides 10 fault insertion channels that can be connected to either (or both) of two fault bus connections.

Fault insertion modules are used within an automatic test system to simulate common fault conditions such as an open, short to ground or a short to other connections in a device under test, Pickering stated. Each fault insertion channel can switch up to 125VDC with powers up to 300W or 250VAC at up to 2.5kVA. Each channel can carry and hot switch at 10A. Both fault buses are rated at 20A enabling the support of two 10A fault conditions from each one.

The 40-199 uses a switch design based around high quality electro-mechanical relays. In addition to being supported in any PXI compliant chassis, it can be supported in Pickering Interfaces modular LXI chassis.

Pickering allows users to choose the size and rating of the fault insertion channels they need from 2A to in excess of 30A. All fault insertion solutions are compatible with the most common real time operating systems, the company added.
