PRECAUTION
Read User Manual before operation.
1. Check carefully all buttons are positioned correctly before startup.
1) Position high power button correctly.
2) Position power switch correctly.
2. Before running the test, all the inputs of amplifier system and all the signal outputs of RTDS
must be checked. make sure all the outputs of the amplifier and all the inputs of being tested
devices are connected properly;
3. Supply capacity should attain the requirement; otherwise it will affect output power of amplifier
during high current output.
4. Print following symbols the packing at where are obvious to see: fragile, handle with care, top
(a arrow pointing up), keep dry and protect from shaking.
5. Generally it’s not necessary to depress high power button (high power button light should be
off also).
6. Never operate live signal and load wires with voltage output to protect the safety of equipment
and human.
7. It is strictly prohibited that amplifier output value exceeds its maximum output value. External
power inputs the amplifier output which is strictly prohibited otherwise the amplifier will be
damaged
8. Three-phase power supply can not be in the situation of lack phase or three phase seriously
imbalance, otherwise the amplifier can not working properly. Please turn off the power switch
immediately, if the lack phase alarm starts.
9. Safety cautions:
1) Amplifier system must be grounded safety to prevent a potential above ground
on enclosure in the event of an electrical fault.
2) Pay attention to the safety of 36V above output to avoid electric shock
accidents.

2. PAC60Bi (PAC60Ci) Current Power Amplifier
2.1 Basic Principle
This current amplifier is a kind of linear current power amplifier targeting at the CT characteristic of
power system, with the strengths of high accuracy, high current and quick response, which
consists of below parts mainly:
1) High-speed differential input circuit for amplifier;
2) Current power amplifier module;
3) Detection and alarm circuit, and each amplifier has a output distortion detection circuit.
4) Protection circuit, which can shut off the amplifier when its temperature is too high and will
let it resume to work when it is cooled down to a reasonable degree.
5) Cooling fan. When the temperature of the amplifier is quite low, the fan will work at low
speed for it’s better for prolonging the service life and reducing the operation noise of the fan.
2.2 Function
1) The differential input circuit can reduce the influence of the common mode noise to make it
possible that use long wires to connect across the amplifier and signal source, which will reduce
mutual effects between all amplifiers during high current output to guarantee the operation safety
of the simulator.
2) When open circuit or waveform distortion occurs in current output, the alarm light of current
distortion on the front panel will turn on.
3) Pause control function (PAUSE). The pause button on the front panel can cut off the signal input
of the amplifier. Press the pause button, the output current will become zero.
4) When the protection is activated, the input of the amplifier will be terminated and the “Overheat”
alarm light will turn on together.

2.3 High Power Current Output
With high power control button depressed, after several seconds, the high power control button
light will turn on. By then the current amplifier can improve 20% of output power. This button can
be used in case there have high current output needed and heavy load applied.
Cautions:
1. Generally it’s not necessary to activate the high power output function, because it
may cause extra heat generated from amplifier.
2. High power output function must be inactivated as soon as the job was done. Never
let amplifier stay in high power output state for a long time.
3. Never activate the high power output function when output terminals are directly short
connected.
4. Never activate the high power output function with DC current output.
5. Never activate or inactivate the high power output function when amplifier is
producing any output.

3. PAV120Bi Voltage Amplifier
3.1 Basic Principle
This voltage power amplifier is a linear voltage power amplifier specially targeting at the PT
characteristics of power system with the strengths of high accuracy, high voltage and quick
response, which consists of below parts mainly:
1) High-speed differential input circuit for amplifier;
2) High-performance voltage power amplifier module;
3) Distortion detection and alarm circuit. Each amplifier has the overload or output distortion
detection circuit. When overload or short-circuit situation disappears, the amplifier can resume to
work automatically.
4) Temperature protection circuit. It will terminate the amplifier as soon as the temperature of
the amplifier reaches the dangerous degree and will let it resume to automatically when it has
been cooled down to a reasonable level.
5) Temperature-controlled fan. Fan will work at low speed if amplifier temperature is certain
low, which is benefit for prolonging its service life and reducing working noise.
3.2 Function
1) The differential input circuit can reduce the influence of the common mode noise to make it
possible that use long wires to connect across the amplifier and signal source, which will reduce
mutual effects between all amplifiers during high current output to guarantee the operation safety
of the simulator.
2) Automatic output voltage distortion and overload detection circuit, which is quite capable to
protect voltage amplifier against output overload or short-circuit fault. When overload and short
circuit situation disappears, the amplifier can resume to work automatically. If overload or
short-circuit occurs, the amplifier will be terminated automatically and the overload alarm light on
the front panel will turn on.
3) Pause control function (PAUSE). The pause button on the front panel can cut off signal input of
amplifier. Press the pause button, the output of the amplifier will become zero.
4) When the overheat protection is activated, the input of the amplifier will be terminated and the

“Overheat” alarm light on the front panel will turn on.
5) 3U0accumulation function. Ua, Uband Uccan be added up to form a 3U0signal to be outputted
via Udchannel.
6) Two gain options. User can accord to maximum voltage output value to select right gain.
