SC2-4

3*400 V two speed transformer fan speed controller

The SC2-4 transformer speed controllers are based on the principle of voltage control with auto-transformers. They are applicable to voltage-controllable motors (400 V, 50/60 Hz) to control the rotational speed (of fans, pumps, etc.). This controller makes it possible to select 2 optimal motor speeds and to switch these by a contact. So, important energy savings and an increase of comfort can be realised. E.g. Day/Night control.

• 400 Vac - 50/60 Hz - from 1,5 up to 11 A
• 2 switches: 5 positions with Off-position
• Several voltage ranges possible
• Indicator light
