Product Description:

For demanding applications, the BDS3-208/30-08-102-4500B2P is a high-performance industrial servo drive. It is manufactured by Kollmorgen. Output current is a crucial specification. The drive has a convection or fan-cooled output current of 30A continuously. This indicates that the drive can maintain a steady current for extended use, which is critical for motor torque and speed stability. For two seconds, the fan-cooled at a peak current of 60A. This peak current supplies power for dynamic operations and enables the drive to manage high torque transients, such as acceleration or abrupt load changes. For applications that need accurate and fast motions, this is essential. The principal DC bus voltage that the drive runs on ranges from 130VDC to 225VDC. This is a crucial element as it establishes the drive's power supply needs.

The ability to integrate the drive with various power supply configurations that are often seen in industrial settings is made possible by a larger voltage range. The switching frequency for the drive's PWM (Pulse Width Modulation) is 10.0 kHz. This frequency influences the motor's smoothness and audible loudness, as well as how quickly the drive transfers power to the motor. Higher frequency results in higher switching losses but smoother operation and less noise. Efficiency and performance are balanced at 10 kHz. Thermal management is another essential component. The internal heat of the BDS3-208/30-08-102-4500B2P is 175W. Controlling this heat is essential to the dependability and longevity of the drive.

Depending on the needs of the application, the drive may dissipate heat using either convection or fan cooling. Overheating, which may result in failure or performance deterioration, is avoided via efficient cooling. The apparent power capacity, or output KVA rating, is another feature of the drive. The drive has a constant output of 6.0KVA and a peak output of 12.0KVA (2 seconds) at 160VDC bus. The ripple frequency of the motor current is 20.0 kHz ± 10%. This ripple, which relates to the variations in motor current, is a feature of PWM drives. Controlling ripple is essential. Motor overheating, decreased efficiency, and issues with other electrical systems might result from excessive ripple. There is a controllable ripple level at the given frequency and tolerance. There are environmental operating requirements for the drive as well.
