• 230 Vac 3ph 50/60 Hz - from 1,5 up to 18 A
• Enclosure: sheet steel, IP54
• Cam switch: 5 positions with Off-position
• Several voltage ranges possible
• Indicator lamp.
• 230 Vac, unregulated output
• Ready mounted cable glands
• Maximal ambient temperature: 35 °C
• The BTRN-3 transformer speed controllers are based on the principle of voltage control with auto-transformers.They are applicable to voltage-controllable motors (230 Vac 3ph 50/60 Hz) to control in 5 steps the rotational speed (of fans, pumps, etc.).
• When choosing a controller it is important to know the maximum current intensity consumption on the taps.  The indicated maximum current can be taken from each tap.
