Model 2790-H Single-module System for Low and High Voltage/Resistance Applications

Part Number: 2790-H
Products available for purchase from our web store may include U.S. pricing displayed and can be ordered online by U.S. customers for end use in the U.S. only.

Key Features and Benefits:
  • Single-instrument solution for continuity and hi-pot type leakage resistance measurements
  • Programmable constant V source (50500V) supports high speed, high resistance measurements
  • Programmable constant I source (050mA) with dry circuit clamp helps prevent device stress or damage during low resistance measurements
  • Modular architecture adapts easily to single or dual inflator testing and to single or dual position test stands and mixed device/signal applications
  • Expandable multiplexer channels for multipin applications
  • Included 6-1/2 digit DMM with wide functionality and broad measurement ranges
  • Intelligent automation support and easy integration with external test hardware
  • GPIB, RS-232, and digital I/O interfaces for flexible controller options
  • SCPI programmable for simple code development and future extensions
  • 2-year calibration cycle of modules minimizes maintenance costs and system downtime

The Model 2790-H is a single-module system designed for both low current and high voltage ohms (10MΩ to 1GΩ) applications. This "base" system provides all the capabilities needed for electrical testing of either single- or dual-stage inflators in single osition test stands (for example, test stands that test only one single- or dual-stage airbag at a time).

With the addition of a Model 7702 40-channel differential multiplexer module (part of the Integra family of switch/measure solutions), the Model 2790-H + Model 7702 opens the door to higher channel count applications, such as hi-pot/continuity testing of connectors, harnesses, and power distribution devices up to 500V (internally sourced) up to 40 channels.

Related Applications:
  • Automotive airbag inflator/module electrical functional tests
  • Seatbelt pre-tensioner actuator/module functional electrical check
  • High speed, parallel soak, dual inflator, or dual test station electrical check
  • Pinched wire, high voltage, insulation resistance testing in automotive seats, avionics, etc.
  • Multipin connector/harness continuity and leakage resistance measurements
  • Multicontact/switch dry circuit continuity and leakage tests
  • Automotive power/fuse center continuity and leakage resistance characterization
  • PCB/PWB and general purpose short/open circuits testing
