Disposal
Do not dispose of electrical appliances as unsorted municipal waste, use separate collection
facilities. Contact your local government for information regarding the collection systems
available. If electrical appliances are disposed of in landfills or dumps, hazardous substances
can leak into the groundwater and get into the food chain, damaging your health and
well-being. When replacing old appliances with new one, the retailer is legally obligated to
take back your old appliances for disposal at least for free of charge.

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.
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.

viii
Safety Symbols
DANGER – High voltage.
Explanation: To avoid injury, death of personnel, or damage to
the instrument, the operator must refer to the explanation in the
instruction manual.
High temperature: This symbol indicates the temperature is
hazardous to human beings. Do not touch it
to avoid any personal
injury.
Protective grounding terminal: This symbol indicates that the
terminal must be connected to ground before operation of the
equipment to protect against electrical shock in case of a fault.
Functional grounding: To identify an earth (ground) terminal in
cases where the protective ground is not explicitly stated. This
symbol indicates the power connector does not provide
grounding.
Frame or chassis: To identify a frame or chassis terminal.

The WARNING sign highlights an essential operating or
maintenance procedure, practice, condition, statement, etc.,
which if not strictly observed, could result in injury to, or death of,
personnel or long term health hazards.
The CAUTION sign highlights an essential operating or
maintenance procedure, practice, condition, statement, etc.,
which if not strictly observed, could result in damage to, or

1. General Information
1.1 Introduction
This manual contains specifications, installation, operation, and programming instructions of
63800 series high power electronic loads. All the machines are tested according to safety
standard EN61010-1: TYPE POLLUTION II and INSTALLTION CATEGORY II.
1.2 Overview of Key Features
Local operation on front panel keypad.
Remote control via GPIB, RS-232C interfaces.
Photo-couple isolation supplies true floating Load.
Automatic fan speed control to reduce audio noise.
Operation modes: CC, CR, CP @ constant load modes; RLC, CP, Inrush Current @
rectified load modes; CC, CR, CP, CV, DC Rectified @ DC load simulation.
Programmable load value, power factor (PF) and crest factor (CF).
Minimum input resistance allows load to sink high current even with low input voltage.
10 sets of memories to save/recall user-definable setups.
16-bit A/D converter with precision measurement.
Short circuit simulation.
Isolated voltage and current monitoring waveforms output.
1.3 Description
The functions of the 63800 series loads are the same except the variations on input voltage,
load current, and power ratings. They provide simulated loading current for the test unit.
They can be operated independently in AC load simulation and DC load simulation.
Figure 1-1 The Front Panel of the Electronic Load
There are two groups of keypads on the electronic load front panel shown in Figure 1-1. They
are Function keypad and Entry keypad from left to right.
