SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation ,
service , and repair of this instrument. Failure to comply with these precautions or specific
WARNINGS given elsewhere in this manual will violate safety standards of design ,
manufacture , and intended use of the instrument.
Chroma assumes no liability for the customer‘s failure to comply with these requirements.
BEFORE APPLYING POWER
Verify that the product is set to match with the line voltage.
PROTECTIVE GROUNDING
Make sure to connect the protective grounding to prevent an electric shock before turning on the
power.
NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding wire, or disconnect the wiring of
protective grounding terminal. Doing so will cause a potential shock hazard that may bring
injury to a person.
FUSES
Only fuses with the required rated current , voltage , and specified type （normal blow , time
delay , etc.）can be used. Do not use different fuses or short-circuited fuseholders. To do so
could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT REMOVE THE COVER OF THE INSTRUMENT
Operating personnel must not remove the cover of the instrument. Component replacement and
internal adjustment can be done only by qualified service personnel.
WARNING LETHAL VOLTAGES. Ac sources can supply 426 V peak at their output.
DEATH on contact may result if the output terminals or circuits
connected to the output are touched when power is applied.
vi

SAFETY SYMBOLS
DANGER - High voltage.
Explanation: To avoid injury, death of personnel, or damage to the
instrument, the operator must refer to an explanation in the instruction manual.
Protective grounding terminal: To protect against electrical shock in case of
a fault. This symbol indicates that the terminal must be connected to ground
before operation of equipment.
WARNING A WARNING sign denotes a hazard. It calls attention to a procedure,
practice, condition or the like which may result in injury or death of personnel
if it is not rightly observed.
ACOUSTIC NOISE INFORMATION
This product has a sound pressure emission (at the operator‘s side) < 65dB(A).

An Overview of the Products
1. An Overview of the Products
1.1 Introduction
The products of Chroma 6400 series, including 6404, 6408, 6415, 6420 and 6430, are highly
efficient AC power sources providing sine wave output of low distortion. The
microprocessor-controlled sine wave oscillator generates accurate and stable output voltage and
frequency. The PWM (Pulse Width Modulation) approach of the power stage provides full
volt-ampere and current rating to loads. The 6430 supplies power up to 3000 VA, the 6420 to
2000 VA, and the 6415 to 1500 VA.
The AC power sources of Chroma 6400 series are considerably smaller, lighter and more
efficient than traditional power supplies with similar capability of outputting power.
This manual includes the specifications, installation procedures, operation instructions and
maintenance procedures of Chroma 6430/6420/6415 programmable AC sources.
