Programmable AC Source 61705 Quick Start Guide
1
1. General Information
1.1 Introduction
The Chroma AC Source 61705 is a high efficiency, 3-phase AC power
source which provides 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
z Local operation from the keypad on the front panel.

Fan-fail.
z Temperature controlled fan speed.
z Built-in output isolation relays.
B. Input/Output
z Selective output voltage (Neutral to Line) with full scale of 150V/300V.
z Input voltage range 61705: 190 ~ 250Vac.
z Measurement of V, I, P, CF and PF.
z Remotely inhibited control.
z AC ON/OFF output signal.
