Speed regulation mode Potentiometer controlled linear speed regulation for precise and smooth adjustment. Why it matters: you can set and maintain the desired speed with predictable response, reducing overshoot and drift in continuous operation. Output current 040 A current capability. Why it matters: supports medium to power loads without needing additional controllers, enabling more versatile motor and device drives. Input voltage DC 955 V input range. Why it matters: broad compatibility with common power sources such as batteries and DC supplies, allowing flexible integration into existing systems. Output voltage Output voltage is linear under load. Why it matters: provides a predictable voltage response as load changes, facilitating stable performance in speed control and testing scenarios. Use scenarios DC motor speed control for robotics or small CNC projects: use the potentiometer to set motor speed, with up to 40 A available for higher torque applications and a wide 955 V power source. Adjustable drive for cooling fans, pumps, or actuators in automotive, robotics, or hobbyist setups: harness the linear load response to maintain smooth operation as load varies. Laboratory or test bench applications: configure a controllable, linearoutput drive from a DC source to study motor behavior, power electronics, or control algorithms under different loads.
