Ametek / VTI Instruments / VXI Technology SM2002 12-Channel, 10A SPST Power Switch SMIP Module

The Ametek VTI Instruments SM2002 is a 12-channel SPST power switch module built on the SMIP interface for VXI-based test systems. Each channel handles up to 10A, making it ideal for power sequencing, multi-subsystem distribution, and high-current switching in automated test equipment. The module integrates directly into VXI chassis for straightforward system integration.
