Keithley 2600B-PM-1 1A / 200V Protection Module for 2635B & 2636B SMUs

The Keithley 2600B-PM-1 200V Protection Module with 1A Clamp 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 220V.

The maximum DC current is 100mA, and the clamp prevents <100µs transient current spikes up to 1A.

The protection module is designed for use with the following lower-voltage SMUs:

• Model 2635B Single-Channel System SourceMeter Instrument - 63-0490
• Model 2636B Dual-Channel System SourceMeter Instrument - 63-0491
