Product Overview
1. Product Overview
1.1 Introduction
Chroma 6400 Series products, including 6404 and 6408, are high efficiency AC Power
Sources that provide sine wave output with low distortion. The microprocessor controlled
sine wave oscillator generates accurate and stable output voltages and frequencies. The
PWM (Pulse Width Modulation) approach of the power stage allows for full volt—ampere
and current rating into loads. The 6408 can supply up to 800 VA, the 6404, up to 375 VA.
The accurate DSP (Digital Signal Processing) measurement capabilities provide
independent verification of operating values, thus reducing the need for external measuring
instruments.
The 6404/6408 Series AC Power Source is considerably smaller, lighter and more efficient
than traditional supplies with a similar output power capability.
This manual contains descriptions of Chroma 6404/6408 Programmable AC source for
specifications, installation procedure, operation instructions and maintenance procedures.
