Soft start can be used to prolong the service life of the voltage and frequency converter. 3. The motor control system is simplified. 4. Reduce mechanical wear and loss. How Frequency Converter Works? Static frequency converter working principle: The electric frequency converter mainly adopts AC-DC-AC mode, which first converts the power frequency AC power supply into DC power supply through the rectifier, and then converts the DC power supply into AC power supply with controllable frequency and voltage to supply the motor. The voltage and frequency converter converts a basic fixed- frequency, fixed voltage sine-wave power (line power) to a variable-frequency, variable-voltage output used to control speed of induction motors. Frequency Converter VS VFD 1.Power Supply: VFD is composed of AC-DC- AC (modulation wave) circuits. Voltage and frequency change proportionally at the same time and can not be adjusted separately, which does not meet the requirements of the AC power supply. In principle, it can not be used for power supply, and VFD is generally used for speed regulation of three phase asynchronous motor. The whole circuit of frequency converter consists of AC-DC-AC-Filter Circuit, so the output voltage and current waveform are pure sinusoidal, which is very close to the ideal AC power supply. Voltage and frequency converter can output the power grid voltage and frequency of any country in the world. 2.Load Test: VFD(variable frequency drive motor) can't use in load tests because of high vibration and electromagnetic noise, large temperature rise, and the instruments can't work normally. So the voltage to frequency converter that can provide a pure sine wave output becomes indispensable power equipment in the laboratory. 3. Converter: A VFD is not a typical converter though it has conversions inside it. A voltage frequency converter would typically convert a DC signal to an AC signal. FAQs of Frequency Converter 1 What is a frequency converter? The frequency converter is one of the electrical control devices that uses frequency conversion technology and microelectronics technology to control AC motor by changing the frequency of the motor working power supply. The inverter is mainly composed of a rectifier (AC to DC), filter, inverter (DC to AC), braking unit, driving unit, detection unit and micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by the interruption of IGBT, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions, such as overcurrent, overvoltage and overload protection, etc. - 2 What is static frequency converter? + 3 What is frequency of conversion? + 4 What are the main parts of frequency converter? + 5 What is the frequency converter working principle? + 6 Which industries need electric frequency converters? + 7 What is a frequency converter used for?

Rule II: Take the advantage of differences between analytes of interest and interferences Rule III: Consider nature of SPE sample matrices, characteristics of analytes and solubility of used solvents Users can select RayCure SPE columns depending on properties of desired analytes and sample matrices as following selection guides. HOW DOES SPE COLUMN WORK? SPE is a conventional and efficient extraction technique, it uses the affinity of solutes dissolved or suspended in mobile phase for stationary phase to separate desired compounds from a mixture. And there are two solid phase extraction mechanisms to obtain target analytes from complex samples, to retain desired compounds in stationary phase or retain impurities in solid phase. Depending on the difference of two mechanisms, SPE procedures could be a bit various. When sample portion passes through SPE column, undesired impurities are discarded with mobile phase, target compounds are retained in stationary phase, then rinse stationary phase with eluents to collect target compounds. It is the most commonly used purification mechanism of solid phase extraction. In the opposite, to retain impurities in stationary phase, target compounds and few impurities are collected in mobile phase when sample portion passes through SPE column. Rinse the stationary phase which impurities is retained with solvents to obtain rest of retained target compounds. This mechanism is mostly used to eliminate fat-soluble impurities of ion analysis and analysis of multiple pesticides in fruits and vegetables. We provide liquid handler, laboratory and analytical supplies, solid phase extraction cartridge, cartridge spe, lab analytical instruments, total laboratory automation system, etc. For more information, please feel free to contact us!
