ARRAY 366XA
SWITCHING-MODE DC POWER SUPPLY
ARRAY 366XA is a series of 500W programmable switching-mode DC power
supplies with RS-232, USB (optional) and GPIB (optional) interfaces. The good
durability, simple operation, low noise, excellent output accuracy as well as the
adjustment from 0V make this series of reliable power supplies the right choice for
many applications. It provides flexible and stable DC power for various design and
test environments.
Versatile Bench-Top Features
＊High definition liquid crystal display
＊Full-featured keyboard and knobs
＊High-efficient switching-mode power supply
＊The same continuous adjustment (0-Vout) as the linear power supply
＊Low ripple and noise which rivals the linear power supply
＊Excellent line and load regulation
＊Up to 10 operating states storage and recall
＊Portable, ruggedized case and flexible system functions
＊Standardized USB interface, optional GPIB and optional USB interface
＊SCPI ( Standard Commands for Programmable Instruments) compatibility
＊Direct setting of I/O Parameters from front-panel

An Introduction to this Manual
General Information
Apart from a general description of your power supply, it provides instructions for
checking your power supply, selecting power-line voltage and connecting to AC
power.
Initial Operation
It ensures that the power supply develops its rated outputs and responds to operation
from the front panel properly.
Front-Panel Operation
It describes the use of front-panel keys and knobs in detail and how to use them to
operate the power supply from the front panel. And it also shows how to configure the
power supply for the remote interface and introduces the calibration features in brief.
Remote Interface Reference
It contains the reference information to help you program the power supply over the
remote interface, and explains how to program for status reporting as well.
Application Programs
It provides some remote interface applications to help you develop programs for your
application.
6
Tutorial
It describes basic operation of the power supply and gives specific details on the
operation and use of ARRAY 366XA power supplies.
Specifications
It lists the power supply’s basic specifications.
