MicroMaster 420 TS-Alarms

The Siemens MicroMaster 420 TS-Alarms functions as an advanced frequency inverter designed for diverse motor control applications. This unit supports input phases of either single-phase or three-phase configurations, accommodating a broad range of setups. The inverter is capable of delivering power between 120 W and 11 kW, allowing it to serve various operational needs.

With an output phase of three-phase, this inverter can provide a frequency output ranging from 0 to 650 Hz, enabling it to control motors efficiently. The device operates on input voltages of either 200–240 V AC or 380–480 V AC, depending on the configuration required for the application.

For braking, the MicroMaster 420 TS-Alarms employs compound and DC braking functions to ensure effective stopping capabilities. Protection features include overvoltage and undervoltage safeguards, which help prevent damage during electrical disturbances. The inverter's control method utilizes V/f and FCC control strategies, ensuring precise management of motor operations with a loop control system based on a PI controller.

Communication with external devices is facilitated by options including BOP, AOP, and PROFIBUS, enhancing its versatility within automation systems. The device also offers three digital inputs with expansion capability, alongside one analog input for accurately measuring voltage or current. Optionally, an integrated class B EMC filter is available to mitigate electromagnetic interference, further enhancing the functionality of the MicroMaster 420 TS-Alarms in various industrial applications.
