Details

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

Brief Introduction:

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).
