Protection Module for Use with Source Meter Instrument

The Keithley Protection Module (PM) is a stand-alone module that protects certain lower-voltage source-measure units (SMUs) that are part of a testing configuration from damage by voltage sources that are greater than 220 V. It is intended for use in applications where a device breakdown or other potential failure could connect the high-voltage output of the High Power System Source Meter Instrument to a lower voltage SMU.
