Chapter 2 Concept for Variable Frequency Power
Supply System
Inverter power supply through AC – DC – AC conversion is called variable frequency
power supply, which differs from variable frequency speed controller and common
AC stabilized voltage power supply. Variable frequency power supply is mainly used
for convert existing AC power network supply into stable and pure Sine power
supply of required frequency. The features of ideal AC power supply are stable
frequency, stable voltage, zero internal resistance and Sine wave form (without
distortion). Variable frequency power supply is close to the ideal AC power supply,
so the developed countries more frequently use variable frequency power supply as
the standard supply, so as to provide the most excellent powering environment for
electrical equipments and easily evaluate their technical performance. There are
two types of variable frequency power supply: Linear Amplification and PWM Switch.
Variable frequency power supply, taking the microprocessor as its core, is
manufactured by MPWM. It is designed using active component IGBT module, and
adopts such technologies as digital frequency division, D/A conversion,
instantaneous feedback and sinusoidal pulse width modulation to make the capacity
of single machine up to 100KVA. The stability of entire machine is added by
separating transformer output. It is featured with strong load applicability, high
quality output waveform, and simple operation, small and light. In addition, this
power supply has many protective functions against short circuit, over current, over
load and over heat to ensure it’s properly operation.

Chapter 4 Method for Selecting Power Capacity
1. Resistance: Power Capacity = 1.1× Load Power
LoadStartingCurrent
2. Induction: Power Capacity = ────────── × Load Power
LoadRatedCurrent
WaveCrestCoefficientfor LoadCurrent
3. Rectification: Power Capacity = ────────── × Load Power

4. Mixed: Please properly select according to the percentage of different loads.
Note: For such inductive loads as refrigerator and air conditioning, the power
capacity should be selected according to the starting power.

Chapter 6 Installation Instruction & Operating
Instruction
6.1 Installation Instruction
1. Determine the input voltage before using the power source.
2. Turn the voltage knob to the minimum voltage, i.e. rotate it counterclockwise to
the minimum position.
3. Before connection to the power source, turn all switches to OFF to make sure
the device has no possible damage.
4. The power source can only be connected when the device specification exactly
match that of the power source system.
6.2 Operating Instruction
1. Check whether control switches, knobs and displays are fine before using them.
2. Turn the power switch to the OFF position firstly.
3. Please determine again whether the input voltage is correct before connection
to the power supply, to make sure the equipment is safe.
4. Internal AC contactor of the power supply picks up about 3 to 5 seconds after
powering on. Press the Start button, and the output LED will light, indicating
there is output voltage from power supply. Press again the Start button, and the
output LED will be off, indicating there is no output voltage from the power
supply.
5. Output Frequency Adjustment: you can turn the frequency selector to any
position without powering on/off. The frequency indicated at fixed position is
output frequency. To slightly adjust frequency, it is necessary to turn the fixed
position to the rightmost and then adjust the spin button.
6. For example: To get the frequency of 52Hz, please firstly turn the selector to the
VAR position, and then adjust the spin button until 52Hz appears on the display.
7. Nominal Voltage Adjustment: Turn the tri-position voltage selector to the Middle
position, and then rotate the cross-type spin button on the right to get the
desired voltage.
8. Connect the load to the terminal block, and press the Start button, and the
output LED will light. In this way, you can easily get all values displayed on the
functional display.
9. Notice (I): Over current, over load, over heat and short circuit protective
devices are supplied with this machine. In case of over current, over load, over
heat or short circuit, the protective circuit will immediately cut off the power and
the buzzer will sound alarm. At this time, please firstly turn the load off, and
then press the button Reset. The power supply begins providing the power after
the alarm stops. Check the load conditions, and then turn the load on after
determining there is no exception.
10. Notice (II): Warning! If it is necessary to make 220V/110V conversion (inside
Lisun Electronics Inc.

door panel), please do it after turning the load off to make sure the equipment
is safe.
11. Notice (III): Warning! If it is necessary to get the frequency of 400Hz or release
the frequency of 400Hz, please make conversion after turning the load off.
