Keithley 7753 High-Voltage Source Switch Module

Overview

The Keithley 7753 is a 1 MΩ high-voltage source/switch module designed for the Keithley 2790 Airbag and Electrical Device Test System. It combines programmable voltage (50–500V) and current (0–50 mA) sourcing with modular architecture for comprehensive insulation resistance and continuity testing of automotive components, including airbag inflators and other electrical devices.

Key Features

• Programmable constant voltage source (50–500V) for high-speed, high-resistance measurements
• Programmable constant current source (0–50 mA) with dry circuit clamp to prevent device stress
• 1 MΩ measurement range for high-resistance applications
• GPIB, RS-232, and digital I/O interfaces for system integration
• 2-year module calibration cycle to minimize maintenance and downtime
• Modular design compatible with 2790 mainframe (supports one 7753 module)

Applications

• Airbag inflator electrical testing
• Insulation resistance measurement
• Conductor continuity verification
• Automotive component high-voltage testing

Included Accessories

• Reference Manual on CD-ROM
• User Manual on CD-ROM
• AC Line Power Cord
• Mini Flathead Screwdriver
