Product Description

EDS1000 series Multi-function universal frequency inverter has 150% rated torque at 1 Hz, meeting the requirement of low noise, high torque, low electromagnetic interference and covering three voltage grades: 220V, 380V and 690V. This kind of frequency inverter is widely used in applications which require high-speed control accuracy, rapid torque response, and high performance at low frequencies. 

Features

  • Infineon IGBT module (German brand) adopted, featuring less failure rate and smaller size compared with single-transistor inverter.

  • Fujitsu CPU (Japanese brand) adopted, characterizing rapid and stable calculation.

  • Mini size, suitable for all kinds of applications

  • Abundant DI/DO and AI/DO

  • 150% rated torque at 1 Hz frequency

  • Built-in PID controller, realizing constant pressure (flux etc.) “One inverter drives multiple devices” control (optional function)

  • 16 (maximum) section speed control

  • 0-20KHz pulse input output interface

  • Spinning traverse function

  • Automatic voltage regulation (AVR) and automatic current limiting function

  • RS485 communication interface (optional part)

  • Multi-frequency input channel selection

  • Closed-loop running control

  • Keypad parameter copy function and password protection function

  • Crystal English display keypad and English operation content indicating.

Applications

High cost performance 3 phase frequency converter, frequency inverter, vfd and vsd for induction motors 

Textiles, plastics, blower, pump, ceramics, electronics, numerical controls, foods processing, weaving, transportation machine, metallurgy machine,  constant pressure water supply, air compressor, air conditioner, music fountain, paper making, chemical mechinery etc.

Q:The laptop power adapter is burned
To be sure, the power adapter has a problem ~ ~ I suggest you if the warranty period to go after the sale of a ~ ~ If the insurance on Taobao Amoy on a ~ ~ ~
Q:In the case of the inverter, why can not the normal operation after removing the gearbox? The motor is 4 pole.
If there is a load, it may be less than the torque. So it can not run.
Q:How does the variable frequency motor output torque at very low frequencies?
50hz the following frequency, u constant, current and frequency is proportional to the frequency down the output current is also down, and torque and current is proportional to the natural torque is small
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
Q:Three-phase two-pole motor can be used to reduce the frequency of the inverter
With the electromagnetic governor can be, cheap only 50 yuan or so
Q:The parameters of the inverter is 4, 6 motor can be used
Inverter parameters are 4, 6 motor can be used. Parameters can be changed, the general inverter has a special number of motor parameters set, as well as the motor speed settings, if the series can not be changed, put the speed out of the necessary amplification of the inverter to enlarge some.
Q:Laptop adapter heat
In fact, as long as the power adapter temperature is within the design range, that is, the temperature in the normal range, the general is not dangerous! So why is the power supply hot? What kind of temperature range is the normal range? Switching power supply conversion efficiency can only reach 75% -85% or so. The answer is here. Switching power supply conversion efficiency is high enough, it is still difficult to find a better way to convert. Switching power supply in the voltage conversion, a part of the energy loss, in addition to a small part of the loss in the form of waves, the majority of the way out of the heat. Switching power supply power is missing, the loss of energy is also missing, the power of the heat is also large. This is why the desktop power supply to add a fan for cooling reasons. We may wish to count, a 100W switching power supply, in the use of how much energy loss in the above!
Q:Motor 2 pole and 4 pole in the inverter with what set to show
The inverter has a parameter that requires you to enter the number of motor poles, see the direct input of the number of poles
Q:Variable frequency conversion frequency difference characteristics based on,
Frequency conversion is better, you can smoothly change the synchronous speed. Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
Q:Can different brands of laptop power adapters be generic?
Power adapter can not use, the key to see two factors. First, the interface must first be the same interface or can not use. Second, the output current, the output current must be strictly consistent, otherwise it would be very dangerous, the laptop overload of the current is very fragile. The final output voltage I personally think can have a difference of type 5V. Because the battery on the voltage requirements up and down can have 5V floating. I have also used a high 5V adapter, has been no problem, but this is just my personal view. Strictly the same as the best. Oh, for reference only! Since you can plug in the normal use, indicating that the interface is consistent, and the output voltage and current are the same. Then I can responsibly tell you, rest assured to use it, there will be no problem.
