Product Description:
Danfoss makes the 175Z0553 Frequency Converter that features a book-style enclosure to save space and make it easy to install in small electrical panels. Its maximum rated input current is 5.3 A, which provides a balance between energy requirements and reliable system performance.
The 175Z0553 converter is suitable for operation with an input voltage range of 3 x 380-500 V, facilitating integration into various three-phase supply networks. Its maximum output power capacity of 4.3 kVA demonstrates its capability for supporting medium-sized loads with high precision in terms of voltage and current control. This converter's energy efficiency is highlighted via a 0.96 efficiency rating that minimizes overall system losses. This converter’s output frequency range is from 0 Hz to 1000 Hz to handle equipment that needs both low and extremely high-speed operation. The 175Z0553 converter delivers an output current of 5.6 A at a voltage of 380-440 V, offering precise load handling and consistent stable operation. Its supply side protection is provided by the incorporation of pre-fuses with ratings of 16/10 A maximum, which protect the input section against electrical overloads. During full operational demand, its power loss is at a minimum of 110 W, ensuring controlled heat production and reducing energy waste.
This converter further incorporates a built-in cooling fan, actively ensuring thermal stability and prolonging the operational life of electronic components under constant utilization. Its IP20 chassis rating offers protection from contact with solid foreign objects, making it safe to operate in conditions where dust and particles are present. This converter also features a Profibus DP fieldbus option to support advanced automation, which allows communication with networked equipment and remote monitoring capabilities. Its cabling is managed through a maximum power cross-section of a 4 mm² (AWG 10) cable, ensuring a connection that satisfies electrical installation needs.
Frequently Asked Questions about 175Z0553:
Q: How does the integrated fan improve performance in 175Z0553?
A: The fan prevents overheating by maintaining steady airflow inside the unit. This helps extend the converter’s operational life under continuous load conditions.
Q: Why is a book-style enclosure used in this model?
A: The book-style design reduces panel space requirements. It also simplifies wiring and accessibility for service or inspection.
Q: What benefit does Profibus DP add to the 175Z0553 converter?
A: Profibus DP allows direct communication with automation networks. It improves system monitoring and remote control integration.
Q: How does an IP20 chassis rating affect installation?
A: The IP20 rating ensures protection against solid objects greater than 12.5 mm. It is suitable for controlled indoor environments without direct exposure to liquids.
Q: Why is power loss limited to 110 W in this product?
A: Limiting power loss reduces heat buildup and wasted energy. This improves both efficiency and long-term cost savings.
