Description

Variable three-phase auto transformer  TLR 350B 5A

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.
