    Details


    Array 3721A USB Programmable DC Electronic Load 400W 80V 40A
      

    Brief Introduction:

    3720A,3721A,3722A and 3723A Electronic Loads provide an adaptable, and functional asset wherever power sources need to be tested.These units are designed to provide high reliability, great performance, and ease of operation with multiple functionality.
     

    Features:    
    • 4 basic functions: CC, CV, CR, and CP ; and 8 basic test modes: CCL, CCH, CV, CRL, CRM, CRH, CPV, CPC
    • High-speedsequence, high-speed transient, short-circuit, battery discharge and other auxiliary functions
    • Minimum operating voltage is less than 0.6V at the load's full rated current
    • Optional zero-voltage test accessories are available
    • Programmable current slew rate
    • Perfect protection assures high reliability in the most complicated of test environments
    • Multiple groups of parameters and lists can be saved and recalled
    • Ruggedized structure, exquisite user-friendly design and convenient operation
    • Supports SCPI (Standard Commands for Programmable Instrumentation) and Labview, and provides necessary PC software
     
     
    Multifunction:
    • Equipped with four basic test functions: CC, CV,CR, CP;
    • High-speed transient operation with separate high/low lever time and rising/falling time control;
    • Powerful sequential test function; with a minimum step time of 10us; and a maximum step time of 10000s. Cyclic numbers can be adjusted freely and a sequence can be chained to another sequence to achieve even more complex test procedures;
    • Providingshort-circuit test, battery discharge test and other auxiliary functions;
    • Remote input terminal and external trigger input terminals are provided. The remote measurement can monitor the input signal automatically, and it is not necessary to change wiring or modify settings during operation;
    • 10 groups of setup parameters can be saved, and providing automatic uploading of preset parameters;
    • By supporting SCPI, it is easy to build an ATE (automatic test equipment) system that works with other programmable instruments via optional RS232, USB and GPIB interfaces.
     
    Advantages:
    • Design optimized for portability and rugged reliability;
    • Logical keypad design and convenient test operation;
    • Easy-to-set test parameters coupled with a powerful sequence editing function;
    • All electronic calibration - therefore no need to dismantle the equipment-chassis;
    • Firmware can be updated online.


    Specifications:
    (The warm-up time is 30 minutes. Specifications indicate warranted performance in the 25°C ± 5°C region of the total temperature range).
