1 General Information
1.1 Product Overview
The 917x and 918x 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.
