Variable Frequency Drive Triol AT24 Line L – comfort and efficiency


Good tidings, dear visitors of our site and  my blog in particular. I would like to continue the topic of elevator frequency drives today and tell you directly about our product in this segment – Triol AT24 Line L.

The given product is presented in the market by capacity from 5,5 kW to 37 kW, it covers all spectrum of powers of elevator drives, including cargo ones. At the same time, the line consists of only three design versions: up to 7.5 kW, 11-18 kW, 22-37 kW.

In this development, we have laid the possibility of operating the inverters in the temperature range from -20 to +40 C with the degree of protection IP20. Dimensions of the line, depending on the power, vary (WxHxD) from 135x265x155 for small power and up to 340x540x240, which makes it possible to install this drive in VSD of any type.

After testing, our VSDs have been successfully implemented and utilized. The possibility of using Triol AT24 in both synchronous and induction hoists has been currently realized. At the same time, synchronous hoists also tested the effective work of this line in the gearless coupling. We are preparing such proposal for induction hoist for the new year.

But there is no limit to perfection, so now the development team has concentrated its efforts on improving the accuracy of the elevator car stop on the floors, as well as increasing the speed of the elevator acceleration without loss of comfort.

For any question or suggestion, write your thoughts in the comments, I will be happy to discuss them with you. Read more about our future news in the following blogs.
