Autotransformers three-phase TLR 3120B 12A
Option Without TK protection
Autotransformer regulators serve the purpose of airflow control, fitted in three-phase ventilation and heating systems.
Transformer speed controllers are based on the principle of voltage control with auto-transformers.
They are applicable to voltage-controllable motors to control the rotational speed.
