Keithley 7753
High Voltage Source/Switch Module 1Mohm
Description
This High Voltage Source/Switch Module is designed exclusively for use in the Source meter switch system for electrical checks of airbag inflators and a variety of other automotive electrical test applications.
These modules provide the programmable high voltage and low current sourcing, plus the multichannel switching support required to measure insulation resistance and conductor continuity in these applications.
It include programmable DC voltage (50 to 500V) and current (0 to 50mA) sources, as well as relay switching.
A built in current to voltage converter on these modules is used with the voltage source to measure the insulation resistance.
They can also be used to measure currents from 0 to 50μA.
