Input Reactor
Input Reactor
AC L series reactors, also known as power coordination reactors, are used to connect in series with the input terminals of fully digital DC speed governors and frequency converters. They are connected between the power supply and frequency converters, and can limit the impact waves caused by grid voltage sudden changes and operating overvoltage, effectively protecting the frequency converter, improving the power factor of the frequency converter, and suppressing the harmonic current input by the frequency converter into the grid.
Output Reactor
Output Reactor
The output reactor is located between the output of the frequency converter and the motor, which can suppress the harmonic and motor noise generated by the frequency converter, and compensate for the charging current of the connected long wires, thus enabling the motor to operate normally even when the leads are long.
DC Reactor
DC Reactor
The DC reactor is used in the DC circuit after rectification. The number of pulses in a rectifier circuit is always limited, and harmonic interference often occurs in the output rectifier voltage. A smoothing reactor is required to suppress it. The converter stations of DC transmission are equipped with smoothing reactors, which make the output DC close to the ideal DC. Flat wave reactors are also indispensable in DC powered thy ri stor electrical drives. The DC reactor is connected between the DC rectification and inverter links of the frequency converter, which can make the operation of the inverter link more stable and improve the power factor of the frequency converter. Refined from imported cold rolled silicon steel sheets, mainly used to improve input power factor, reduce input high-order harmonics, and reduce external conduction and radiation interference.
Input Filter
Input/Ouput FILTER
Input (output) filter is a passive low-voltage filter that can effectively suppress conducted interference propagating along power lines, while also greatly reducing radio frequency interference generated by electronic equipment. The materials and components used have been tested in the worst environment, and do not require fans. It is installed on-site and easy to operate, suitable for all brands of frequency converters.

Sine Wave Filter
Sine Wave Filter
The sine wave reactor is driven by a PWM frequency converter, and its switching frequency range is between 2—8Hz to provide sine wave output voltage. In frequency converter driving applications, it can effectively suppress high-frequency losses and DV/ DT radio frequency interference, improve the performance and lifespan of the motor, and grow the cable of the motor and frequency converter to 500 meters, up to 3 kilometers.
