Get Wholesale AC Frequency Converter in Stock

As the professional manufacturer, SPX would like to provide you high quality AC frequency converter.

Core function

AC - DC - AC is the mainstream of general AC frequency converter, through the "AC rectifier to DC filter, AC inverter" three-step transformation, realize the output voltage and frequency of the precise coordination control.

Core features

1.Smooth speed regulation: based on the formula n = 60 f/p, by changing the output frequency to adjust motor speed, wide speed range, high precision, and can realize step less variable speed.

2.Soft start and soft stop: starts gently ascending frequency/voltage, hard to avoid motor start current shock, reduce the damage of power grid and mechanical transmission parts; When the machine stops, the deceleration time can be set to prevent equipment failure caused by load inertia.

3.Energy saving and consumption reduction: for quadratic loads such as fans and water pumps, the speed can be adjusted according to the actual working conditions, replacing the traditional throttle/cut-off mode, and the energy saving rate can reach 30%~50%.

4.The torque control: by means of vector control or direct torque control mode, can be adjusted independently and excitation torque of the motor load torque, high accuracy, high dynamic response of load demand.

5.The protection and monitoring: built-in over current, over voltage, under voltage, overload, open phase, overheating, such as multiple protection function, and can monitor the running parameters such as current, rotational speed and power support fault alarm and record.

Application field

High quality AC frequency converters, with strong adaptability and flexible control features, are widely used in various motor drive scenarios in both industrial and civil fields.

1. General industrial loads such as fans, water pumps, compressors, conveyors, and mixers are the core equipment for energy-saving renovations.

2. High-precision transmission scenarios: CNC machine tools, steel rolling equipment, lifting machinery, elevators, and automated production lines rely on vector control to achieve precise positioning and speed regulation.

3. Hvac and construction fields: Central air conditioning water chillers, cooling tower fans, and building supply and exhaust systems achieve constant temperature and pressure control through frequency conversion regulation.

4. The city and the people's livelihood project: water supply pump, sewage aeration equipment, mine ventilator, the continuous and stable operation of the adaptation complex working conditions.

5.Supporting new energy: photovoltaic water pump, wind power propeller system, the electric car driver, realize two-way power flow combined with energy feedback unit.
