DollaTek DC Motor Speed Controller, 7-70V 30A PWM, Adjustable 12V-48V, with 30 Amp Fuse & Flexible Cable, ELA16153, Electric Circuit Testing Device

• Wide voltage input 7-70V, maximum output current 30A (Please refer to the recommended power range for actual use current. It is recommended that 12V within 250W, 24V within 350W, 48V within 450W, and 60V within 500W. )
• The knob has a switch function, which can control the motor speed from 0% to 100%. Adjustable potentiometer flexible cable can be separated, the cable length is 15CM.
• It adopts imported high-voltage MOS tube, three 100V high-frequency low-resistance capacitors, car fuses, and the parameters are not easy to heat and can be replaced. The standard aluminum casing protects internal circuits and components for long-term durability.
• The power of the input power supply must be greater than 1.5 times the rated power of the motor to make the motor work (note: the input voltage and the rated voltage of the motor must be consistent).
• Optimized circuit design Wide adjustment range of duty cycle, smooth adjustment of the motor without bath noise, no vibration, with power indicator, stable circuit design, suitable for long-term work.

Specification: DC Motor Speed Controller Applicable voltage range: DC 7-70V Drive current: max. 30A (Please refer to the next section "" Control power (recommended)" " for actual use current) Control power (recommended): - 12 V: within 250 W. - 24 V: within 350 W. - 48 V: within 450 W. - 60V: less than 500W. Duty cycle adjustment range: about 1%-100% PWM frequency: 12 KHz Shell size: 85 mm x 58 mm x 32 mm. Note: 1. This product is DC brush motor speed controller. It must be equipped with a DC power supply to power the regulator. It can not be connected to the mains power and cannot drive the brushless motor. 2. Before turning on the wiring, please read the wiring label and the input is direct current. The positive and negative poles should not be wrong! The output connection to the motor (motor) does not need to be divided into positive and negative. If the direction of rotation is incorrect, please change the two wires of the motor.
