Product Description:

The 175Z7464 is a Frequency Converter designed for precise and energy-efficient motor control in HVAC systems. It delivers a rated power output of 3.7 kW (5 HP). This makes it suitable for fans, pumps, and air-handling equipment. This unit by Danfoss supports a three-phase AC input voltage range from 380 V to 460 V. The drive supports 50 Hz to 60 Hz of frequency.

The input current rating of the 175Z7464 frequency converter varies depending on the applied voltage. It consumes 9.1 A of current at lower voltage levels and 8.3 A at higher voltages. The output voltage is adjustable from 0 V up to the input voltage to enable flexible motor speed regulation. The drive supplies an output current ranging from 10 A at partial load to 8.2 A at full load capacity. It supports a programmable output frequency range from 0.1 Hz up to 1000 Hz. This allows fine-tuned control over a wide operational spectrum. The 175Z7464 frequency converter includes a built-in DC-link reactor to reduce harmonic distortion. This improves current quality and overall system efficiency. An integrated RFI filter ensures electromagnetic compatibility. It complies with EN 55011 Class A standards when paired with a 150-meter screened cable. A detachable Local Control Panel (LCP) is included to feature a four-line LCD display. This offers simplified configuration, parameter programming, and real-time monitoring. The RS-485 communication supports Modbus RTU, Metasys N2, and Johnson Controls FLN protocols.

The 175Z7464 frequency converter incorporates dual PID controllers. It is capable of managing two independent process feedback inputs for precise environmental control. The Automatic Motor Adaptation (AMA) and Automatic Energy Optimization (AEO) functions enhance efficiency. The drive supports operating temperatures up to 40°C (104°F) and tolerates up to 95% relative humidity in non-condensing conditions. Its IP54-rated enclosure meets UL and NEMA Type 12 standards.
