Product Description:

The 178B7251 drive is engineered to offer reliable performance with an apparent balance of power, efficiency, and safety features. It is manufactured to run under a condition of overload at 110% for one minute, providing the ability to support sudden peaks without affecting stability and safety. This ensures that dependent processes using the drive are able to continue operating smoothly when there are momentary spikes in load.

One of its best features is its 0.97 efficiency rating, which indicates high energy conversion with low waste. It also saves costs and supports energy-sensitive industries. This unit has a power rating of 9 kVA. It comes with a current rating of 13 A. The drive has versatile enclosure solutions to match installations in various environments. When paired with an IP20 enclosure, it only weighs 6.6 kg, making it easy to handle and fit into compact protected cabinet installations. For more severe or exposed applications, the IP55 or IP66 enclosure models offer greater resistance to dust and water, with the device weighing 14.2 kg in these options. This flexibility allows it to be used in different areas. It is good for contained indoor areas and extreme sites. The approximate power loss is 187 W. It gives performance capability and efficiency. This gives credible output without unnecessary energy consumption.

Further, it shows considerate engineering with respect to both performance and extended-term energy management. Moreover, the 178B7251 gives efficiency along with overload protection and enclosure versatility. It also comes with a power rating that is conducive to steady operation. The light and heavy-duty structures ensure that it will be able to satisfy particular site demands. It gives reliable and better drive outcomes in multiple applications.
