DC240-36/48-4Q

DC-4Q Series

The DC-4Q series of drives are DC in/DC out PWM chassis drives capable of four quadrant reversing and braking. This series of drives is ideal for portable battery powered equipment. The DC-4Q has the ability to maintain variable speed even as battery decreases and has a sleep mode for extended battery life while not in use. The four quadrant capability allows simple connections for fast reversing and/or braking without the need for bulky contactors or braking resistors. The 1.01 form factor produces clean DC output for efficient and quiet motor operation. Like all Minarik Drives products, these units are built in the USA.

The DC-4Q series of drives have adjustments for IR Compensation, Motoring Current Limit, Regenerative Current Limit, Forward Max Speed, Reverse Max Speed, Min Speed, Deceleration and Acceleration Time. These drives are microprocessor based meaning these ranges can be reprogrammed to meet any custom needs. The DC-4Q series also has Power and Fault LEDs, including current limit, under voltage, overheat and short circuit.

The DC-4Q is available in two models, one for 12-24V systems, the other is designed for 36-48V systems. For simplicity and safety, no jumpers or switches are required for selecting voltages.
