1. General Information
1.1 Introduction
The series of Chroma AC source 61605 are high efficiency AC power source which provide
sine wave output with low distortion, and accurate measurement of power. The DSP
microprocessor 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.
1.2 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-Current, Over-temperature, Fan-fail.
Temperature-controlled fan speed.
Built-in output isolation relays.
B. Input/Output
Selective output voltage with full scale of 150V/300V/Auto.
Remote control by the use of analog voltage reference.
Measurement of V, I, P, CF, PF, Vdc, Idc, Ipk, Is, VA and VAR.
Remotely inhibited control.
AC ON/OFF output signal.
1.3 Specifications
The operation specifications of the model 61605 are listed below (on the next page). All
specifications have been tested according to the standard Chroma test procedures. All
specifications are based on a remote sense connection, 25 ± 1°C, and resistor load unless
specified otherwise.
