Overview

3.1 Introduction

Chroma 63200 series electronic loads are suitable for design, manufacturing, testing and
quality assurance.    It contains a processor, GPIB and RS-232C connectors, front panel
keypad, display, and power stage.    Its built-in remote control function allows you to control,
read back current, voltage and status.    The Save/Recall feature allows you to save up to 100
files, 10 programs, and one default setting.    All of them can be saved in load EEPROM for
future use.

The load contains four cooling fans. The fan speed increases or decreases automatically when
the load power rises or falls.    This feature reduces the overall noise level as the fans do not
always run at the maximum speed.

Each load can operate in constant current (CC), constant resistance (CR), constant voltage
(CV), and constant power (CP) modes.    If the application is larger than one of DC load can
provide in power or current rating, the DC loads operation in parallel is a suggested way.
However, it can be applied in CC mode, CP mode and CR mode.

Front Panel Description

The front panel of the load includes a 20

×

2 characters LCD display, three segment LED, 9

led status indicators, and keypads. The LCD display will show which function is being
performed when you use the keypads. One of the keys has two functions. Figure 3-1
shows the front panel of the loads.
