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 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.
1. Lethal voltage. AC source may output 426 V peak voltage.
2. Touching the connected circuit or output terminal on the front or
rear panel when power is on may result in death.
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.
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.
The Notice sign denotes important information in procedures,
applications or the areas that require special attention. Be sure to
read it carefully.

ix
Protection Plates
In order to protect the terminals of the Chroma 61500/61600 AC power source from damage
during shift or transportation, users can choose to install the enclosed rear panel protection
plates (2 pieces) as an option.
Installation Instruction:
1. Remove the 4 screws from both sides of the rear panel (Figure 1).
2. Mount the protection plates with the screws included in the bag (Figure 2).

1. General Information
1.1 Introduction
The series of Chroma AC source 61601/61602/61603/61604 are high efficiency AC source
which provide 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
●Local operation from the keypad on the front panel.
●Remote operation via GPIB or RS-232C interface.
●Protection against Over-power, Over-Current, Over-temperature, Fan-fail.
●Temperature-controlled fan speed.
●Built-in output isolation relays.
B. Input/Output
●Selective output voltage with full scale of 150V/300V/Auto.
●Remote control by the use of analog vol0tage reference.
●Universal of input voltage range 90Vac ~ 250Vac.
●Measurement of V, I, P, CF and PF.
●Remotely inhibited control.
●AC ON/OFF output signal.
1.3 Specifications
The operation specifications of the model 61601/61602/61603/61604 are listed below (on the
next page). All specifications have been tested according to the standard Chroma test
procedures. All specifications are based on a remote sense connection, 25 ±1°C, and
resistor load unless specified otherwise.
