1. Introduction
1.1 Product Overview
Chroma 61511/61512/61611/61612 Series is a highly efficient
programmable AC Source, which provides a low distortion sine wave
output for power accuracy. The DSP microprocessor generates an
accurate stable output voltage and frequency. The PWM designed
power stage allows apparent power into loads. Its front panel has a RPG
(Rotary Pulse Generator) and keypad control for setting the output voltage
and frequency, while the LCD gives users complete operating status.
Remote programming is accomplished by the GPIB bus, RS-232C serial
port or USB port.
1.2 Key Features
A. Configuration
• Local operation by the keypad on the front panel
• Remote operation via GPIB or RS-232C or USB interface
• Remote control a terminal on front or rear panel using the
Chroma Digital Controller A615101 (optional)
• Protection against over power, over current, over temperature
and fan failure
• Thermostatically controlled fan speed
• Built-in output isolation relays
B. Input/Output
● Selectable output voltage with full scale of 150V/300V/Auto (3
ranges)
● Analog (simulation) reference voltage for remote control
● V, I, Po, CF, PF, Idc, Vdc, Vac, Iac, Ipk, Vpk and VA
measurements
● Remote inhibited control
● AC ON/OFF output signal
