Variable Frequency Drive Triol AT24 line SR

Variable Frequency Drive Triol AT24 line SR is specifically designed for controlling sucker-rod deep-well pumps (SRP) with of 5.5-75 kW power range. This VFD contains all the necessary components, such as the power drive part, well controller UMKA-07 or P24E control panel with Triol induction power (patent No. 2014116615 dated 05/05/2018), a circuit breaker with a handle on the cabinet door and a three-phase socket (optional), placed in single IP55 enclosure operating at −40…+50 °C.

Triol AT24 VFD line SR is furnished with a built-in algorithm for working with SRP without the use of braking resistors, and, it can be completed with options supplied in a separate cabinet, if necessary. It’s possible to customize VFD control modes by means of an analog / digital reference or using automation using Modbus RTU / TCP protocol and remotely monitor and control all the processes by the means of Triol HIVE system. Moreover, you are able to complete additional units and options placed in a separate cabinet (passive filter, du/dt filter, circuit breaker, three-phase socket, bypass circuit).
