1. Safety Precaution
Read User Manual before operation.
1. Check carefully all buttons are positioned correctly before startup.
1) Pause button in correct position in pressed state.
2) ON/OFF in OFF state.
3) Not press high power button (High power indicator in OFF state)
2. Main supply capacity should meet the requirement; otherwise it will affect output power
of amplifier during high current output.
3. Handle the amplifier with great care and follow the symbols on the package: fragile,
handle with care, top (an arrow pointing up), keep dry and protect from shaking.
4. Generally it’s not necessary to depress high power button (high power button light
should be off also).
5. Never operate live signal and load wires with current output to protect the safety of
equipment and personnel.
6. In case the power outlet for powering up the amplifier does not have protective
ground customer must connect the ground socket to the protective ground at the
test site
7. The voltage output of over 36V is considered as dangerous and care must be
taken
8. It’s not allowed to feed external voltage into the current output sockets
9. It’s not allowed to feed external current into the current output sockets
10. Disconnect the external circuit from the relay to avoid any influence to the test
11. Do not block the ventilation outlets

12. Avoid the equipment to be wet by rain
13. Do not switch-on and operate the equipment in the place having explosive gas or
water vapor.
14. The 500V dangerous voltage can be in the equipment and please don’t remove
the cover by yourself
15. Please contact the manufacture for any maintenance
16. The guarantee will become invalid if kit is opened by the customer

For Your Safety Please Note
This symbol indicates potential hazards by electrical currents caused by, for example,
wrong connections, short-circuits, technically inadequate or faulty equipment or by
disregarding the safety notes of the following sections.
Use Proper Power Cord
Only the power cord designed for the instrument and authorized by local country could be
used.
Ground The Instrument
The instrument must be grounded safely with the supplied ground cable.
Observe All Terminal Ratings
To avoid fire or shock hazard, observe all ratings and markers on the instrument and check
your manual for more information about ratings before connecting.
Do not Assemble/Disassemble the Instrument without
Authorization
The instrument should be assembled and or disassembled by professional engineers; users
are not allowed to perform related operations except for some possible replacements in this
manual.

Do not Move or Maintain the Instrument When it is Powered On
To avoid personnel injuries, any position adjustment, maintenance or parts replacement are
forbidden when instrument is on.
Use Proper Fuse
Please use the specified fuses.
Do Not Operate With Suspected Failures
If you suspect damage occurs to the instrument, have it inspected by qualified service
personnel before further operations. Any maintenance, adjustment or replacement
especially to circuits or accessories must be performed by authorized personnel.
Keep Well Ventilation
Inadequate ventilation may cause increasing of temperature or damages to the device. So
please keep well ventilated and inspect the intake and fan regularly.
Do Not Operate in Wet Conditions
In order to avoid short circuiting to the interior of the device or electric shock, please do not
operate in a humid environment.
Do Not Operate in an Explosive Atmosphere
In order to avoid damages to the device or personal injuries, it is important to operate the
device away from an explosive atmosphere.

Keep Product Surfaces Clean and Dry
To avoid the influence of dust and/or moisture in air, please keep the surface of device clean
and dry.
Operate the Instrument in a Suitable Environment
The best condition for optimal measurement is: 5 ℃to 40℃; less than 2 ℃/hour changing,
20% to 80% RH and the instrument should not be placed towards the air outlet.
Electrostatic Prevention
Operate in an electrostatic discharge protective area environment to avoid damages
induced by static discharges. Always ground both the internal and external conductors of the
cable to release static before connecting.
Proper Use of Solvent
Please use the solvent in compliance with instructions specified in its supplier. If necessary,
wear protective clothing, gloves and glasses to avoid any injuries.
Handling Safety
Please handle with care during transporting to avoid damages to surface, panel and parts
resulting from the falling from your hand.

NOTE: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense.

2. General
The real-time simulation technology is widely used in the power system. Different digital
simulation system are developed such as RTDS, EDF and TEQSIM, etc. But no matter how
the digital simulation or digital-analog model simulation changes, the power amplifiers are
the main component in the system.
The power amplifier for digital simulator in power system is required to have high linearity,
quick response, be available to all kinds of capacitive, inductive and resistive loads.
Generally power amplifier consists of two types of amplifiers: linear power amplifier and
switching power amplifier. The linear power amplifier has the strengths of high linearity,
quick response, high accuracy, good electromagnetic compatibility and the weakness of bad
performance in high current and high power cases. The switching power amplifier is quite fit
in high current, high power devices with its strength of high efficiency, but it’s weak in
linearity, small signal noise, DC offset, drift, transient response, load driving capability
aspects, which are very difficult to fix.
PA460Bi-C amplifier is specially designed for power electricity simulation and solves the
high power problem for linear power amplifier and accuracy problem for heavy current
output.
PA460Bi-C amplifier has six-phase current output. Each phase maximally outputs 15A
RMS and maximum output power of 135VA.
