AC Industrial Frequency Converter 37KW Booster Pump Drive VFD Inverter
Introduction of frequency converter
1. Choose first-tier suppliers in the industry for capacitors, fans, electronic components, PCB boards, etc.,
to ensure the health and stability of the product throughout its life cycle. Using imported Infineon IGBT,
2. The operation is simple and convenient.
3. Built-in RS485 interface. And supports the Modbus communication protocol.
4. Strong overload capacity, 150% rated current for 60 seconds, 180% rated current for 10 seconds; 200% rated current
for 0.54 seconds.
5. The four fault records can effectively record the maximum current, maximum voltage, and maximum temperature of
the last four times, which is helpful for customers to analyze and deal with faults and improve after-sales efficiency.
Instructions for peripheral devices of frequency converter
| Name | Instruction |
| The power supply | The input 3-phase AC power supply shall meet the scope specified in this manual |
| The circuit breaker | Purpose: It can cut off the power supply and protect the after-stage when the after-stage equipment has abnormal over-current.
Selection: the breaking current of the circuit breaker is selected as 1.5 ~ 2 times of the rated current of the frequency converter. The time characteristics of the circuit breaker should be selected according to the time characteristics of the overload protection of the frequency converter. |
| Leakage protector | Purpose: Because the output of the frequency converter is PWM high-frequency chopper voltage, so the high-frequency leakage current is unavoidable.
Selection: B type special leakage protector is recommended. |
| Contactor | In order to ensure safety, please do not close and disconnect the contactor frequently, which will cause frequency converter breakdown.
Do not control the start and stop of the frequency converter by closing and disconnecting the contactor to the system, which will reduce the life of the frequency converter. |
| Input AC reactor or DC reactor | Improve power factor and the influence of three-phase input AC power imbalance on the system to suppress high harmonics. Reduce the external conduction and radiation interference, and effectively suppress the influence of pulse current on the rectifier bridge. |
| Input filter | Reduce the conduction interference from the power supply end to the frequency converter, and improve the frequency converter's anti-interference ability.
Reduce the external conduction and radiation interference of the frequency converter. |
| braking unit and braking resistor | Purpose: When braking, it can effectively consume the energy of motor feedback and realize fast braking.
Selection: Refer to recommended resistance and power for selection of braking resistors. |
| Output filter | Reduce the external conduction and radiation interference of the frequency converter |
| Output AC reactor | Effectively avoid damage to motor insulation due to harmonic voltage and reduce the frequency converter frequent protection due to leakage current
When the connection between the frequency converter and the motor exceeds 100 meters, it is recommended to mount an output AC reactor |
| Motor | Select the motor matching with the frequency converter |
