FUNCTIONAL CHARECTARISTICS
- New space vector technology
- The excellent algorithm ensures the realization of low-frequency high torque, high-efficiency grid voltage utilization and optimized sine wave output under the premise of minimum switching loss, so as to reduce the working noise and heat generation of the motor.
- Special software dead time compensation
- Effectively deal with the low-frequency pulsating torque of the VFD to ensure the smooth operation of the motor.
- Excellent speed tracking self start without speed sensor
- Be able to start the running motor to ensure the smooth and continuous operation of the user’s equipment.
- The VFD can automatically identify the speed and realize stable speed tracking.
- Various operation modes
- It has multiple modes of automatic operation, manual parameter operation and power frequency operation according to the settings (such as setting the water pressure sensor according to the required water pressure, special cables and other accessories are provided by the manufacturer). It can automatically save energy in the mode of automatic and manual setting according to the setting, and has the function of power factor adjustment. It can dynamically adjust the power factor according to the change of load, so as to save more energy.
- Voltage fluctuation suppression
- The dynamic automatic voltage control (AVC) function ensures that when the input voltage fluctuates by ± 30%,
- The output voltage fluctuation is less than ± 5%.
- The self-contained three-phase current transformer and voltage transformer have the protection design of overvoltage, overcurrent, undervoltage, IGBT short circuit, inverse time overload, etc. in addition, it can be safely protected under the condition of load short circuit and grounding.
- Special under load protection function for water pump
- The unique load self-test function can reduce the risk of pump burning when the water pump idles without water.
- Rich terminal application functions and signal receiving ports can meet the functional applications in different occasions. The unique holding brake control function makes the operation of the load more stable and efficient.
- Provide digital input, analog input, analog output and digital output, and have the remote communication interface with the third party in accordance with the protocol of Mod-bus. It can realize remote monitoring and control functions.
- The operation panel of the VFD can carry out various control operations and parameter settings. The display screen of the external panel is displayed in Chinese, with data storage and replication functions
- Within the speed regulation range of 30-100%, the power factor at the input of the frequency conversion system reaches more than 0.96 without any power factor compensation.
- The VFD can be configured with two sets of motor parameters and can be switched through terminals.
- Carry out the test in any direction within 1 meter away from the VFD, and the measured noise of the frequency converter shall not exceed 50 dB.
