Catalog excerpts
Autotransformer three-phase fan speed controllers Rated current SEC: Rated voltage PRI: Control type: Autotransformer, industrial fan speed controllers serve the purpose of airflow control in three-phase fan motors controlled by voltage. Mounted in industrial ventilation or heating installations. A knob placed on the metal housing panel is used for the five-step speed setting. Equipped with an independent switch and an alarm lamp. The control circuit of the regulator is protected by a fuse. Built-in frost protection (FS contacts) and thermal motor protection (CT contacts). The transformers are made with Class II insulation and protection grade IP21, maximum ambient temperature 25°C, thermal class of insulation B (130°C). Manufactured in compliance with EN61558-2-13. ul. Postępowa 25/27, 93-347 Łódź, Poland tel.
