he frequency converter is also called voltage and frequency converter. CCS has mastered the most advanced frequency conversion speed regulation technology. We can provide customers with high ingress protection converter, high ingress protection transformation converter, and explosion-proof variable frequency converters, which are widely used in special environments such as oil and gas, chemical industry, and coal mines. The power frequency converter has the characteristics of high reliability, high protection, and high efficiency, and meets the needs of customized frequency converters. Types of Frequency Converter High IP Converter Solid State Frequency Converter 50HZ to 60HZ Because of its high cabinet protection level, the frequency converter can be installed outdoors and is suitable for complex outdoor operations. Power Transformation High IP Converter High Voltage Frequency Converter 50HZ 10kV/11kV/13.8kV Input voltage is 11kV or 13.8KV and it can output 2 or 3 curcuits which runs 2 or 3 motors at same time. Explosion Proof VFD Explosion Proof Variable Frequency Drives 1140V 75kW / 660V 110kW With explosion proof certificate,this kind of VFD is allowed to run in the undermining environment.The voltage is from 380V to 1140V. Frequency Converter Application 1. Voltage and Frequency Converter for Cooling Tower: The use of a voltage and frequency converter on a cooling tower fan is the most useful means to control leaving water temperature on critical process water applications. Frequency Converter can help save energy and reduce the noise of cooling tower in non- peak periods and benefit the life of the frequency converter components with fewer starts, smoother starts, and built-in motor diagnostics. 2. Voltage and Frequency Converter in Mining Applications: Voltage and frequency converter are now finding wide use in mining applications. 3. Voltage and Frequency Converter for Water Pumps: The installation of voltage and frequency converter on water pumps can be an effective energy saving measurement. Voltage and frequency converter can be installed on all water pumps, including those associated with HVAC systems. Benefits of Using Frequency Converters 1. Speed regulation and saving energy, which can save energy by lowering the motor speed when it is not necessary to run at full speed. 2. 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. Qingdao CCS Electric Corporation is a professional power control equipment company, we provide electrical control equipment, vfd frequency converter, vfd electric motor and etc. Want to know frequency converter application and What is a frequency converter used for, contact us.
