Product Description:

The 178B1328 HVAC Drive is specifically intended for delivering maximum performance for heating, ventilation, and air-conditioning applications that demand constant output and high-quality control. The drive features a nominal output current of 54 A and has stable operation in a wide range of HVAC applications.

With a nominal power of 30 kW at 400 V three-phase and 37 kW at 480 V three-phase, the drive provides compatibility with diversified supply arrangements. The maximum supply voltage it can support is 528 V AC, thus making it adaptable in regions where the electrical standard is different. Its IP20/NEMA 1 enclosure rating gives it general protection against careless contact and minimal dust entrance, suitable for indoor installations in limited spaces. The drive is air-cooled, and this simplifies thermal management and reduces the demands for external cooling means. Designed for fault-tolerant applications, it can withstand ambient operation to 45°C with no impairment of performance. In addition, it is approved for installation at altitudes up to 1000 meters and thus readily deployable in a wide variety of geographical locations. The ability of the 178B1328 to offer communication flexibility is also an important feature, with fieldbus support for DeviceNet and optionally other fieldbuses, thereby making integration into existing control networks very easy. It has good components that are better for new systems and HVAC tasks. It has current handling capacity, power ratings, and fieldbus communication.

Compact yet potent, the 178B1328 delivers efficient motor control without sacrificing demanding operating conditions. It is able to manage power supply, stability, and better communication. This gives a reliable solution that keeps the HVAC system in good operating condition. It is an efficient and reliable unit working under variable conditions.
