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 voltage or 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 voltage/current output sockets
9. It’s not allowed to feed external current into the current/voltage 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 voltages/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 in testing.
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

PA30Bi-H Power Amplifier User Manual

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
Real time digital simulator technology has broad applications in power system test and
research nowadays. As the computer technology and the research of power system
simulator are improving, several different kinds of digital simulator systems are coming
out continuously, such as RTDS, EDF, TEQSIM, etc. However, power amplifier, as the
final output in simulator system, will always be the most important part of full digital
simulator or digital-analog simulator, no matter how they have changed.
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.
PA30Bi-H can produce 3-phase current, with maximum RMS phase current of 30A and
maximum output power of 450VA, and 4-phase voltage, with maximum RMS phase
voltage of 250V and maximum output power of 75VA.

3.1 Power Supply
Power supply 3 phase 380V AC 50/60Hz
Power capacity
1800VA
Note:
The instant current while running the amplifier is 7-10 times of the rated current, as a
result, the power supply should be more than 10 times of the total power.
It is suggested the total power supply by PAP02 should be not less than 5 times of the
total power of all the amplifiers installed on the same panel
It is suggested power on each amplifier on the same panel with interval 5 seconds.
