Product Description:

1.Technical specification

  

1). Voltage class: 380V

 

2). Range of power: 0.4KW~450KW

 

3). Stable and reliable Control Mode

 

(1) VF control: Multiple curve could been chosen, Linear V/F curve, 2.0 times power drop torque V/F curve, custom V/F percentage(can realize manual energy saving control), multipoint VF curve. This apply to the situation that one frequency inverter drives multiple motors, such as fan, water pump, engraving machine, injection molding machine etc.

 

(2) Open-loop vector control: Steady speed with high precision, wide range of speed governing, as the speed ratio is 1:200 and 180% rated torque could be output in 0.5Hz. Good dynamic performance.

 

Open-loop vector is suitable for high-Performance universal occasions such as machine tools, centrifuges, cranes and handling equipment, rolling mill and other loads.

 

(3) Torque control: Fast torque response,<20ms, precision torque: <5%, applied to winding, drawing and other occasions.

Q:Can the HP laptop's power adapter be universal?
Power supply low-voltage plug to the same, the voltage to the same, the current is greater than or equal to can be used
Q:How to view the parameters of the notebook power adapter on your computer
Control Panel - System - Hardware - Device Manager - Network Adapter, right click, and the menu appears. If it is infinite, then first follow the above argument to see if it can be enabled. Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
Q:Quartet of the TA, TC terminals have positive and negative?
This can not be said to be positive and negative, should be called the public, TA, is the common.
Q:Laptop power adapter how to detect?
No load voltage, DELL plug more special, the middle needle no load measurement is no voltage, the outer ring outer house and the wall only 19.5V voltage
Q:How does the variable frequency motor output torque at very low frequencies?
Low frequency, the motor torque is relatively low, generally VF inverter performance is good or bad, the price level reflected in this time. But there is torque to enhance the function, it will not move without moving. If no load can not start, check the motor card and other mechanical problems such as whether there is a problem.
Q:What is the application of variable frequency speed control?
In the second half of the 20th century, the power electronic devices from the SCR (thyristor), GTO (gate can be turned off thyristor), BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT (electrostatic induction transistor ), SIT (Electrostatic Inductive Thyristor), MGT (MOS Control Transistor), MCT (MOS Control Gate) to today's IGBT (Insulated Gate Bipolar Transistor), HVIGBT (High Voltage Insulated Gate Bipolar Thyristor), Device To promote the continuous development of power conversion technology. Since the 1970s, pulse width modulation variable frequency (PWM-VVVF) speed control research has aroused people's attention. In the 1980s, the PWM model optimization problem, which was the core of the frequency conversion technology, attracted people's interest and made many optimization modes, in which the saddle-wave PWM mode was the best. The 20th century, the late half of the 1980s, the United States, Japan, Germany, Britain and other developed countries VVVF inverter has been put into the market and widely used.
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
Or the star of the three-phase motor to the corner, so that after the rectifier inverter into a 220-volt three-phase AC ...
Q:Computer frequency changer to do cd frequency changer how points positive and negative
. In this circuit, the total capacitance is 6500 microfarads, the voltage is doubled.
Q:Do you want to pay attention to the number of poles of the motor when selecting the inverter?
Inverter is generally selected by the power, do not consider the number of poles, but the inverter output current is controlled by the module, so you can choose in the selection as much as possible in accordance with the rated current to select the inverter. And left redundant party B overload and other phenomena.
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
11KW the following can be brought, the inverter rectifier module may be broken,
