Control cabinets with automatic air cooling are designed for control and protection of electric motors of the fans of automatic air-cooling system. One electric motor is controlled with r.p.m. control depending on the temperature of the product at the output of the automatic air-cooling system, the other electric motor is controlled with a TeSys T relay without rpm control.
Large fan inertial mass leads to heavy start and long-lasting flow of inrush current with all the consequences (mechanical impulse load, current overloads of switching units and the decrease of their life). Fluid temperature control mechanism requires intermittent switching on/off of the fans.
To improve performance Characteristic of the electric drive of the automatic air cooling system a frequency-regulated drive (FRD), a frequency converter, is used, that makes it possible to:
