Catalog excerpts
Three-phase two-speed fan speed controllers Rated current SEC: Rated voltage PRI: Control type: Three-phase autotransformer fan speed controllers applicable to voltage-controllable motors to control the rotational speed of fans and ventilation systems. Regulators are equipped with two indicators - the green one shows when the regulator is on while the red one shows when the TK contact is on. These controllers make it possible to select two optimal motor speeds and to switch these with a contact. Important energy savings and an increase of comfort can be achieved, for example by day and night control. Regulators are fitted with TK contacts for thermal motor protection and run/stop contacts for remote control. Made with Class II insulation and protection grade IP21, max ambient temperature 25°C, thermal class of insulation B (130°C). Manufactured in compliance with EN61558-2-13. ul.
