Keithley 2290 Power Supplies and a Model 2290- PM-200 Protection Module protect both user and instrumentation from hazardous voltages. An interlock circuit built into the power supplies can be used to ensure that the output voltage is disabled if a high voltage test fixture access door is open. In addition, all Series 2290 power supplies have low voltage analog outputs to permit safe monitoring of the high voltage and the output current.
When low voltage measurement instrumentation is used in the high voltage circuit, the protection module safely clamps the voltage across the instrument to a maximum value of 200V even when a device under test (DUT) breaks down. Thus, a Series 2290 Power Supply, Model 2290- PM-200 Protection Module, and Keithley accessories provide all the elements for building a safe, high voltage test environment.
