Soft start device for asynchronous motors

AE-technology soft start and braking device, AE-P50 series controls the voltage change and ensures smooth start and stop of three-phase short-circuited rotor asynchronous motors with power from 15 to 220 kW.

The device is designed for use as part of mechanisms for which reliability, ease of installation and management, ease of commissioning and minimization of acquisition costs are the most important requirements.

The AE-technology AE-P50 device contains a full set of electric motor protection functions and ensures that all starting parameters are kept within safe limits. The resulting smooth starting (accelerating) characteristic makes it possible to exclude overheating of the engine, the appearance of peak (shock) loads in the power supply network, as well as to significantly extend the service life of the equipment due to the elimination of sharp jerks of the mechanical part of the drives.

Areas of application:

• Center-mounted and piston pumps
• Fans
• GW compressors
• Conveyors
• Special mechanisms (mixers, mixers)

Engine control functions:

• Management in three phases
• Does not have a built-in bypass contactor.
• Control of the electric motor according to the linear law during the entire period of acceleration and braking
• Built-in MODBUS bus with RJ45 connection

Protection functions:

• Indirect thermal protection of the engine
• Thermal protection of the UVP itself
• Control of the correctness of alternating phases
• Determination of phase break
