It is a 1000W Frequency Controller PWM DC Motor Speed Controller, Working Voltage: DC 10V~50V, Rated Current: 30A, It has small size, high efficiency, long term stable and reliable quality,easy installation and use, Especially Suitable for DC Motor and other equipment etc.

Parameters:

• Working Voltage: DC 10V~50V (output voltage is 0~100% of input)
• Rated Current: 30A
• Maximum Current: 40A
• Controlled Power: 360~1000W
• Speed Regulation Range: 5% ~100%
• PWM Frequency: 240Hz, 2.2kHz, 22kHz
• Potentiometer: B50K resistance, 8mm opening
• Dimension: 108 x 55 x 38 mm
• Weight: 150g
• How to select PWM frequency:
• 1-OFF, 2-OFF to choose 22KHZ, the rated current is 15A, no noise, powerful at low speed, suitable for high speed;
• 1-ON, 2-OFF to choose 2.2KHZ, the rated current is 20A, a little noise;
• 1-ON, 2-ON to choose 240HZ, the rated current is 30A, a little noise, suitable for low speed motors(less than 3000vpm).

Note:

• 1. Speed regulator input of DC motor is direct current, and can't connect to alternating current.
• 2. The positive and negative pole of DC power supply can't connect reversely, or speed regulator will be damaged.
• 3. Potentiometer's knob can change output's duty ratio of speed regulator, thus change motor speed.
• 4. For convenient transportation, we put damping material into package, please take it out after receiving the product.

Package Includes:

• 1 x PWM DC motor controller ( Power Supply Module )
