Which high-power low-voltage inverter to choose?
Thread Content
For the 110kw fan circuit, an inverter is required. What is the quality of domestic inverters in the high-power range? What is the cost-performance ratio? It would be great if you could recommend some good domestic brands. By the way: How are the frequency converters from Shenzhen Sifang?
For high-power low-voltage frequency converters, it’s better to choose imported premium brands as they are more reliable; domestic or foreign lesser-known brands come with many problems!
A Fuji product should be fine. Our factory has several 110KW fans driven by Fuji frequency converters.
Our company uses Sanken frequency converters, and they have been in use for many years without any problems..
Domestic products are generally of average quality; you can now use Fuji Ta, Meidensha, or Boshi without it costing much.
You can inquire about the price of Fuji; its control parameters and adjustments are very simple and straightforward, making it easy to operate. Even ordinary workers here can handle it.
Everyone worships foreign things; I’m the same. Foreign products are simply more reliable and trustworthy! Actually, domestic options are also good
If Party A’s conditions are not favorable, it is recommended to choose a first-tier domestic brand. The 110KW inverter is fine. For example: Lideafu, Renauld, etc
Does Lidehua Fu have low-pressure versions? I don’t know, really I don’t know; please advise! I’ve used domestic Hielpu models, and they’re fine. Siemens’ 430 and 440 series models are not expensive either; basically, they’re all of domestic production, which is good. ABB’s models have a user-friendly interface and stable quality. In short, compare brands at the same price, and compare prices for the same brand
Use the ABB ACS510 series – it offers an excellent cost-performance ratio. Its price is already close to that of Japanese brands. The major domestic brands such as Inovance, INVT, Huifeng, and Puchuan are also comparable. If there are many precision instruments in the vicinity, and electromagnetic interference is a concern, it’s better to choose a European brand
