The FTRmac series of high-voltage motor intelligent soft start devices integrates vacuum circuit breakers, high-voltage soft starters, and bypass switches into one solution. It is mainly used for controlling the start and stop of AC asynchronous motors with rated voltages ranging from 3.3KV to 10KV, frequencies of 50/60Hz±5%, and rated powers from 250kW to 3150kW. This product boasts powerful functions, including multi-channel programmable digital input and relay output signals, as well as multi-channel programmable analog input and output. It also supports Modbus/RTU and Profibus-DP protocols, ensuring strong product compatibility and seamless connection with external device signals. Employing superior motor control technology, the product integrates motor start, data acquisition and display, motor protection, and soft stop functions into one unit. Its unique vertical touch screen display interface allows for easy access to historical data curves or data, making operation simple and more efficient.
