Product Description:
The 178B2009 Drive accepts a broad supply voltage within the range of 380 volts to 460 volts, with an acceptable tolerance of ±10%. Manufactured by Danfoss, it is robust to relative humidity of up to 95 percent non-condensing, tested to IEC 721-3-3 class 3K3 environmental compliance standards.
The 178B2009 HVAC drive provides a conversion efficiency rating of 96 percent, ensuring lower electrical loss and optimized power utilization in prolonged HVAC operation. During operation at 441 to 460 volts, the input current taken by this HVAC drive is 11 amperes with specified conditions. Its matched frequency range is between 50 hertz and 60 hertz, with an acceptable deviation of plus or minus one percent to ensure electrical stability. Its power usage is optimized with a displacement power factor of more than 0.98 to keep operation near unity and reduce wasted reactive power. The 178B2009 HVAC drive is designed with book-type housing, a compact and thin enclosure, enabling effective use of installation space in various configurations. The supported mounting options by this drive are panel mount and wall mount, thus providing flexibility for various HVAC installations, depending on site layout requirements.
This drive accommodates a 300-meter maximum motor lead (unscreened), which is ideal for high-voltage system applications where high cable extension distances are needed. This drive is vibration tolerance compliant for 0.7 g RMS within an 18-hertz to 1000-hertz frequency range, providing mechanical integrity under operating stress. For input precision, this HVAC drive incorporates two analogue signal inputs, each engineered with its own resolution (10-bit + sign) for high system control capability. The acceleration and deceleration cycles of this HVAC drive can be adjusted with programmable ramp times of 1 second to a maximum of 3600 seconds.
Frequently Asked Questions about 178B2009:
Q: How does the book-type housing design in HVAC Drive 178B2009 help in installations?
A: The slim housing minimizes required panel space and allows efficient integration in compact control cabinets. It enables easier layout planning for dense HVAC electrical setups.
Q: Why is the 0.7 g RMS vibration tolerance in 178B2009 significant for HVAC environments?
A: This tolerance protects internal electronics from long-term mechanical stress. It ensures reliable performance even when installed near equipment producing consistent vibrations.
Q: What advantage does the 10-bit resolution analogue input provide in this drive?
A: It offers fine-grained signal detection accuracy for precise system control. This resolution ensures smoother motor response to varying HVAC demands.
Q: How does the wide motor lead length capability benefit the 178B2009 HVAC Drive?
A: With up to 300 meters unscreened length, installations can span large buildings. This reduces limitations on equipment placement in distributed HVAC systems.
Q: Why is a displacement power factor greater than 0.98 important for this drive?
A: It minimizes wasted reactive power, lowering operating costs. This ensures closer-to-unity performance and more efficient energy usage.
