DC Motor Speed Controller PWM 7-70V Switch Regulator 30A

SPECIFICATIONS Applicable voltage range: DC 7-70V (70V is the maximum operating voltage please leave margin while using) Drive current: Maximum 30A(Current need to reduce relatively while working voltage is high) Recommended control power: 12V within 300W ; 24V within 400W ; 48V within 450W ; 72V within 500W Adjustable duty cycle range: About 1% -100% PWM frequency: 12KHZ APPLICABLE SCENE 1. Need a wider speed range. 2. Need fast dynamic response process. 3. Automatic smooth transition is required during acceleration and deceleration. 4. High torque is required when low speed operation is required. 5. Good excavator characteristics are needed, which can automatically limit the overload current to the set current. 6. It is a DC Motor Speed Controller, not a Voltage Controller.
