Product Description:

The 131B9522 is a Danfoss VLT Drive designed for efficient and reliable motor control in heating, ventilation, and air conditioning systems. It is built to offer intelligent automation tailored to HVAC demands, ensuring precise management of fans, pumps and ventilation motors. The drive is rated for a 5.0 horsepower capacity, the amount of mechanical load that it can effectively control. This unit can handle both active and reactive power demands and comes with an apparent power rating of 6.93 kVA. This capacity ensures that the drive can deliver stable electrical output even when load conditions fluctuate.

The 131B9522 offers a visual interface for managing key functions, providing a simple monitoring and control experience. The display ensures that users can easily monitor real-time performance data, adjust settings or diagnose issues from a centralized interface. This drive is also designed to offer compatibility with strict EMC regulations. Its RFI suppression filter is rated for Class C1, ensuring robust suppression of electromagnetic interference during operation. This prevents disruption to nearby sensitive electronic equipment, supporting safe integration into environments with multiple electronic devices.

The 131B9522 drive has a space-saving footprint with a frame of A2 size. It is built with an E20 enclosure, which provides a protective housing for the drive’s internal components. This enclosure is designed to shield the drive from environmental factors such as dust, accidental contact, and other potential installation risks. This ensures safe and reliable operation in standard indoor environments. The drive runs efficiently on a flexible input range of between 380 and 480 VAC. This allows it to adapt to different installation environments, maintaining consistent performance and efficiency in HVAC systems across various building infrastructures.
