Model 2790-H

정밀 DC 전류 소스

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.

Model 2790-H의 주요기능

Single-instrument solution for continuity and hi-pot type leakage resistance measurements
Programmable constant V source (50~500V) supports high speed, high resistance measurements
Programmable constant I source (0~50mA) 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
