1.1 Product Overview

The 917xB and 918xB series are high-performance dual range linear

DC power supplies that provide clean and reliable power with high

resolution and accuracy. All models are programmable via standard

USB interface or optional RS232, GPIB and LAN interface. Interface

cards and I/O cards come in a modular form factor. Selected models

feature high voltage outputs or dual channels to provide

series/parallel tracking functionality. All models include front and rear

panel outputs for flexibility, and feature programmable list mode for

storing and running customized test sequences. Additionally, a

unique LED test mode function can be enabled for LED test

applications requiring minimal inrush current output. These power

supplies are suitable for bench or rack mount operation with the

available rack mount kit option.
