Operation Overview

Introduction
The Chroma 63200A Series Electronic Loads are suitable for design, manufacturing, testing
and quality assurance for electronic products. The load contains a set front panel keypad, a
VFD, two system bus ports, two USB ports and an optional GPIB card (to be purchased).
The user is able to use the built-in remote control functions to readback the current, voltage
and other status. The store and recall functions can save up to 256 files, 10 programs and a
group of default settings, and all data can be saved in the FLASH memory of Electronic Load
for later use.
The Electronic Load is equipped with heat sink fans that can control the temperature
intelligently to reduce overall noise level when the Load temperature rises or falls.
A load can operate independently in CC, CR, CV and CP mode. If your application requires
the power or current capacity more than an Electronic Load can provide, multiple Electronic
Loads can be used by connecting in parallel.
The Electronic Load allows the user to input the UUT spec including V and I for GO/NG
check. Moreover, the VFD shows the measurements and deviation of specifications in real
time to lead the user to adjust the setting parameters.
This chapter covers the descriptions of front and rear panels, initial settings and load
operations in different modes.
