1. General Information
1.1 Introduction
This manual describes five major things of the Chroma 6460/6463/6490 programmable ac
source. They are specifications, installation, instructions on operation and theory of
operation. In the manual the term, AC source, is applied to the Chroma 6460/6463/6490
programmable ac source.
1.2 Description
The series of AC source is a high efficiency programmable ac power source, which is capable
of simulating a wide variety of AC line conditions and accurate measurement of power. The
microprocessor-controlled waveform oscillator generates accurate, stable output voltage and
frequency. The PWM design of power stage allows for full volt-ampere into loads. The
front panel has both RPG (rotary pulse generator) and keypad controls for setting the output
voltage and frequency. The LCD provides a complete operating state of the unit to the user.
Remote programming is accomplished either through the GPIB bus or the RS-232C serial
port.
1.3 Key Features
A. Configuration
 Local operation from the keypad on the front panel.
 Remote operation via GPIB or RS-232C interface.
 Protection against Over-power, Over-load, Over-temperature, and Fan-fail.
 Temperature-controlled fan speed.
 Built-in output isolation relays.
B. Input/Output
 Selective output voltage with full scale of 150V/300V for 6463/6490, and
150V/300V/500V for 6460.
 Remote control by the use of analog voltage reference.
 Full-page display of setup and measurement results.
 Measurement of V, I, F, P, CF, and PF.
 AC ON/OFF output signal
