1. General Information
1.1 Introduction
The series of Chroma AC source 61601/61602/61603/61604 are high efficiency AC 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 vol0tage reference.
● Universal of input voltage range 90Vac ~ 250Vac.
● Measurement of V, I, P, CF and PF.
● Remotely inhibited control.
● AC ON/OFF output signal.
1.3 Specifications
The operation specifications of the model 61601/61602/61603/61604 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.
