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
