Product Description:

The DMC-50720-EXT-24V is a high-performance servo drive designed by Danaher to regulate motor speed and torque with precision. It converts electrical input into a controlled output, using pulse-width modulation to deliver smooth and efficient motion control. By optimizing power distribution, it enhances motor efficiency and supports dynamic load changes. This servo drive is widely used in CNC machines, conveyor systems, and other applications that require high precision. This unit comes with a 20A peak capacity for handling short bursts of high power when needed. This capability makes it compatible with applications that need quick speed changes, load changes or quick position adjustments.

The DMC-50720-EXT-24V provides a continuous power output of 3.4 kW, ensuring stable and reliable performance in demanding motion control applications. This sustained power delivery allows the servo drive to maintain consistent motor operation without overheating or efficiency losses. It offers an impressive efficiency rate of 95%, ensuring that the input power is effectively converted into useful output. The drive is suited for an input voltage of 570 VDC (+10% / -20%), which allows it to function reliably at 456 VDC to 627 VDC. This flexibility ensures compatibility with different power supply conditions.

The DMC-50720-EXT-24V features a speed linearity of <1%, ensuring precise and consistent motor speed control. This high level of accuracy minimizes speed fluctuations, which is essential for applications requiring stable and repeatable motion. By maintaining near-perfect speed linearity, the servo drive enhances system efficiency, reduces mechanical wear, and improves overall process reliability in automation and motion control tasks. This model operates with a switching frequency of 4 kHz, meaning it switches power to the motor 4,000 times per second. This high-frequency switching ensures more precise motor control by minimizing torque ripple for smoother motor operation.
