Features:*DC Motor Speed Controller AC Input 220V DC Output 180V DC Governor*Fits for DC motors under 400W*With soft start function: When the motor is suddenly powered off during operation, the motor will start slowly (soft start) when it is called again, preventing the instantaneous high current from burning the motor*With stepless speed regulation function, the speed regulation linearity is good, and it has constant torque performance at low speed, that is, when the motor rotates very slowly, the force is still very large*Easy to install and operateSpecifications:*Input voltage: AC 220V 50Hz*Output voltage: DC 0-24 0-36 0-48 0-90 0-110 0-180V (adjustable)*Output Power:When the output voltage: DC 0~24V, the power: ≤60WWhen the output voltage: DC 0~90V or DC 0V~180V, the power: ≤120W*Control method: Forward*Installation method: V panel screw installation*Dimension: 10060112mm (Approx.)*Opening hole dimension: 8254 90-2φ4.5mm (Approx.)Package Contents:1*DC Motor Speed ControllerNote: The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
