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.

BEFORE APPLYING POWER
Verify that the power is set to match the rated input of this
power supply.
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.) should be used.
Do not use repaired fuses or short-circuited fuse holders. 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. The instrument should be used in an
environment of good ventilation.
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 1. Lethal voltage. AC sources can supply 426 V peak at their
output.
2. DEATH on contact may result if the output terminals or
circuits connected to the output are touched when power is
applied.
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.
High temperature: This symbol indicates the temperature is
now higher than the acceptable range of human. Do not
touch it to avoid any personal injury.
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
The WARNING sign denotes a hazard. It calls attention to a
procedure, practice, or the like, which, if not correctly
performed or adhered to, could result in personal injury. Do
not proceed beyond a WARNING sign until the indicated
conditions are fully understood and met.
CAUTION The CAUTION sign denotes a hazard. It may result in
personal injury or death if not noticed timely. It calls
attention to procedures, practices and conditions.
ACOUSTIC NOISE INFORMATION
This product has a sound pressure emission (at the operator‘s side) <
65dB(A).

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
zLocal operation from the keypad on the front panel.
zRemote operation via GPIB or RS-232C interface.
zProtection against Over-power, Over-current, Over-temperature and
Fan-fail.
zTemperature controlled fan speed.
zBuilt-in output isolation relays.
B. Input/Output
zSelective output voltage (Neutral to Line) with full scale of 150V/300V.
zInput voltage range 61705: 190 ~ 250Vac.
zMeasurement of V, I, P, CF and PF.
zRemotely inhibited control.
zAC ON/OFF output signal.
