FAQ
Frequently Asked Questions
Our Products >>
1What types of products does Mingch have?
We have single-phase voltage stabilizers, three-phase voltage stabilizers, wall-mounted voltage stabilizers, VFD, power inverters, transformers and other products.
2What material is used for the coil of the voltage stabilizer produced by Mingch?
Customers can choose (copper + aluminum) or all copper according to their needs.
3What types of display meters does Mingch voltage stabilizer have?
Analog meter, digital display meter, touch screen.
4What is the difference between the SBW series three-phase voltage stabilizer and the TNS series three-phase voltage stabilizer?
The main difference is the internal structure. The TNS series voltage stabilizer uses a coil structure, while the SBW series voltage stabilizer uses a copper column structure. When the load is large, the SBW series voltage stabilizer is more stable, while the TNS series voltage stabilizer has a price advantage.
5What is the input range of Mingch's voltage stabilizer?
We provide customized services. Customers can choose the input range according to their actual situation. For example, the input range of a single-phase voltage stabilizer can be 220V±15%, 220V±20%, or even a wider range.
6What is the voltage regulation accuracy of Mingch voltage stabilizer?
The voltage regulation accuracy of our conventional products is ±3%. If customers require products with higher accuracy, we can also achieve ±1%.
7What protection functions does Mingch's voltage stabilizer have?
Our voltage stabilizers have overvoltage protection, overcurrent protection, undervoltage protection, short circuit protection, overload protection, etc.
8Do you have certificates?
Yes, we have CE, ISO9001 certifications.
9What is the MOQ?
This depends on the product's specifications and model. For example, for some high-power products, we can sell even just one unit.
10What is the difference between a relay type voltage stabilizer and a servo type voltage stabilizer?
The relay type voltage stabilizer has a simple structure and a relatively low price, but the voltage stabilization accuracy is not high and the response speed is slow. It is suitable for occasions where the voltage changes infrequently or the equipment requirements are not high. The servo type voltage stabilizer has higher voltage stabilization accuracy and more stable performance, and can cope with occasions where the voltage changes frequently, but its price will also be higher than the relay type.
11What types of VFD does Mingch have?
We have single-tube type, igbt type and solar type.
12What equipment can Mingch's VFD be used with?
In addition to elevators, any type of fan and water pump can use our VFD.
13What types of transformers does Mingch have?
We have oil type transformer, dry type transformer, Isolation transformer and autotransformer.
14What type of conductor is used in Mingch’s transformer?
Copper or Aluminum.
15Do you have solar inverters?
Yes.In addition to solar inverters, we also have pure sine wave inverters and modified sine wave inverters.
16What product options do you offer based on the customer's voltage range?
Our standard products have an input voltage range of single-phase 160-250V and three-phase 304-456V. If the customer's voltage falls below this range, we also offer products with a wider input range, including ultra-low voltage options.
17Can the product be customized?
Yes, we can customise the product parameters according to the customer's requirements.
