Keithley is a world-leading manufacturer of precision electrical test and measurement equipment, specialising in solutions for semiconductor testing, materials research and electronic characterisation. Its portfolio includes source measurement units (SMUs), digital multimeters, electrometers, picoammeters, data acquisition systems and switching solutions. Trusted by engineers, scientists and researchers worldwide, Keithley instruments deliver exceptional accuracy for low-level measurements and advanced electrical testing applications.
2657A-PM-200 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.
The protection module is intended for use in applications where a device breakdown or other potential failure could connect the high-voltage output of the Model 2657A High Power System SourceMeter Instrument to a lower voltage SMU.
