Pickering Interfaces expands PXI high-power solid-state switch range

Dec. 15, 2014

Pickering Interfaces, a provider of modular signal switching and instrumentation for use in electronic test and simulation, has introduced two new PXI high power solid-state switch modules to its range of PXI switching solutions.

The Model 40-184 PXI 25-A solid-state SPST switch offers 3- or 6-off SPST solid-state switches capable of handling 25-A signals at up to 100 V.

The Model 40-185 PXI 1.5-A solid-state SPST Switch offers 3- or 6-off SPST solid-state switches capable of handling 1.5-A signals at up to 400 V.

Both of these new PXI switching modules use solid-state switch designs based on isolated MOSFET technology to provide solutions capable of switching very high-power AC or DC signals without any lifetime degradation while used within their ratings. The solid-state SPST switches feature a fast operating time of less than 250 µs and bounce-free state transitions that can handle high inrush currents on switching without any impact on lifetime.

These new switching modules are particularly suited to use in PXI applications where higher voltages and powers are required. Applications include testing products used in transportation systems where mechanical relays are generally unsuitable because of limited switching capacity at the voltages and currents required.

For each model the 3-off SPST versions occupy one 3U PXI slot while the 6-off SPST versions require two 3U PXI slots. Each model uses robust high-power D-type connectors that are fully supported by Pickering Interfaces’ range of connection accessories. The modules can also be supported in Pickering Interfaces’ LXI Modular chassis’ for users preferring Ethernet control of switching systems.

Pickering Interfaces offers a standard three-year warranty and guaranteed long-term product support.
