Product Description:

Pacific Scientific manufactures the SCE903-001-1A, a high-performance servo drive for precise control in industrial automation applications. It combines advanced energy-absorbing technology with smart power control to make sure it works reliably. The drive is designed to fit easily into systems that need strong motor control and the best performance.

The SCE903-001-1A servo drive can absorb 27 J of energy from a 650V standard bus through its bus capacitance. It can handle motor power line lengths of up to 50 meters and has an output current ripple frequency of 4 kHz. For 350 microseconds, the shunt regulator gives off a peak power of 8 kW. It also gives off 50 W of power continuously when cooling by airflow and 100 W when cooling by forced air at 50°C. The servo drive makes sure that very little energy is lost by having a power stage efficiency of 96% at constant power. Extras such as choice cards, work environments, and instructions are included to make setup easier. Its base servo software code makes sure that motor control is stable and accurate.

The SCE903-001-1A can handle up to 8 kW of power at its peak and 50 W of power continuously when it is cooled by airflow. The drive works with motors that have an inductance of at least 2.0 mH, so it can handle a wide range of motor types. This drive is a reliable option for demanding applications because of these features. The SCE903-001-1A is a great example of precision engineering and operating efficiency. For your ease, Wake Industrial provides this servo drive with a year of replacement warranty and a global shipment option to make it available to customers worldwide.
