Notes:
Read User Manual before operation.
1. Carefully check all buttons are positioned correctly before startup.
1) Pause button in correct position in pressed state.
2) ON/OFF 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. Never operate live signal and load cables with voltage or current output to protect the
safety of equipment and personnel.

1. General Description
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.
PAC60Bip is specially designed for R&D of power system simulation. It solves the problems
of high power of linear power amplifier and accuracy of high current output. It is adapt to
various capacitive and inductive load.

3. Functions and Features
3.1 Basic Principle
PAC60Bip consists of the below parts mainly:
1) High-speed differential input circuit for amplifier;
2) Current power amplifier module;
3) Detection and alarm circuit: each amplifier has output open-circuit and distortion
circuit detection.
4) Protection circuit: Turn off the amplifier when the temperature is too high; It will
resume working when it is cooled down to a reasonable degree.
5) Cooling fan: when the temperature is quite low, the fan will work at a low speed for
prolonging the fan’s life-span and reducing working noise.
3.2 Functions and Features
3.2.1 Differential input circuit
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 output to guarantee the operation safety
of the simulator.

3.2.2 Open-circuit alarm function
When one current output is open-circuit or wave distortion, the alarm “I1, I2, I3”in“Current
Output” on front panel will light.
3.2.3 Pause control function
The pause button on the front panel can cut off amplifier’s signal input and amplifier output.
pressing the pause button to pause the output of the amplifier.
The input signal should be stopped before the Pause is removed. The amplifier output will
be restarted with new input signal.
3.2.4 Overheat protection function
When the overheat protection is activated, the amplifier will stop working automatically and
the “Overtemp” alarm light on the front panel will work.
