Product Description:

The Danfoss 131B7648 HVAC Drive is designed to deliver reliable motor control while ensuring compliance with modern electromagnetic standards. It features an integrated RFI filter as class A1/B (C1) which reduces radio frequency disturbance and protects surrounding equipment's.

The 131B7648 HVAC drive is relatively compact with a depth of 200 millimeters which is advantageous when space inside control panels or equipment rooms is tight. It has an intermittent current value of 17.6 amperes at which it can handle spikes above the normal running current for a limited time without damage. While it operates, it generates extra heat of about 255 watts and therefore proper ventilation, or cooling will be necessary to maintain reliability and efficiency. It is designed with a protective grade of IP 55, also known as NEMA type 12 which means it is shielded from dust that could interfere with operation. It can be connected to alternating current systems anywhere from 380-480 V which covers common industrial three phase networks worldwide. The apparent power demand of this drive is 11.1, measured in kilovolt amperes which describes the amount of power the electrical infrastructure must be able to provide.

This 131B7648 HVAC drive can sustain its 7.5 kilowatt output even when slightly overloaded up to 110% of its nominal value. It can continuously deliver 16 amperes of electrical current during steady operation which reflects the standard workload capacity. Its motor capacity is 7.5 kilowatts and is typically aligned with medium size fans, blowers, or compressors in air handling units. It comes with a basic control panel featuring a numeric display and buttons which allows operators to program settings, monitor status and troubleshoot easily.

Frequently Asked Questions about 131B7648:

Q: How does the 131B7648 HVAC drive handle short-term current surges?

A: It allows a brief rise above normal current levels, which supports motor startup demands. This prevents nuisance tripping during fan or compressor acceleration.

Q: Does the 131B7648 HVAC drive require special cooling arrangements?

A: Yes, since it produces noticeable internal heat, airflow or cabinet ventilation is recommended. Without cooling, excess heat can shorten component life and reduce efficiency.

Q: How does the input voltage range affect flexibility in system design?

A: The wide range allows compatibility with standard industrial three-phase supplies worldwide. This reduces the need for voltage adaptation or custom equipment.

Q: Why is apparent power (kVA) relevant when specifying this drive?

A: It helps determine the proper sizing of transformers, cabling, and breakers. Ignoring kVA ratings can cause undersized supply lines and voltage drops.

Q: What applications suit the 131B7648’s power capacity?

A: It can reliably control medium-sized fans, pumps, or blowers in HVAC systems. These are common in air-handling units and chilled water loops.
