BTRNTK-4 • Speed controllers with motor protection

• Hand control of the speed of controllable motors with PTO

• Supply: 400 Vac - 50/60 Hz - from 1,5 up to 11 A
• Enclosure: sheet steel, IP54
• Cam switch: 5 positions and Off-position
• Several voltage ranges possible
• Indicator lamp.
• 230 Vac, unregulated output
• Ready mounted cable glands
• Maximal ambient temperature: 35 °C
• With TK contacts for thermal motor protection
• The BTRNTK-4 transformer speed controllers are based on the principle of voltage control with auto-transformers. They are applicable to voltage-controllable motors (400 Vac, 50/60 Hz) to control in 5 steps the rotational speed (of fans, pumps, etc.).
