Product Description:
Danfoss is a global manufacturer delivering energy efficient technologies and drive solutions worldwide. The company provides reliable products supporting industrial automation, HVAC, water and renewable sectors. The company drives ensure optimized motor performance, reduced power consumption and enhanced process efficiency.
The 175Z7441 Frequency Converter is designed for precise motor control. It has a high efficiency of 0.95 and delivers dependable performance under varying loads. The unit features an IP20 enclosure that ensures protection for general indoor applications. Its weight is 35 kg and at maximum load, the power loss is rated at 426 watts. The converter delivers an output current of 24.2 amperes under normal conditions. It also supports a short time peak output current of 26.6 amperes for 60 seconds. The output power of the model is rated at 10.1 kVA at 240 volts. The converter can operate using an external 24 V DC supply. This allows the control card and option cards to function independently. When connected, the system enables full operation of the Local Control Panel (LCP). The supply connection provides parameter setting without requiring mains power. A low voltage warning is generated when the 24 V supply is active. However, no tripping occurs under this condition. When using both the DC supply and mains supply, a minimum 200 milliseconds delay is required in parameter 111.
The control unit LCP in this 175Z7441 frequency converter functions as a complete operating and programming interface. It is detachable and can be installed up to three meters away. The panel supports a mounting kit option for flexible positioning. Its functions include display, keys for display mode and keys for parameter programming. The indicator lamps and dedicated operation keys are included for monitoring and operation.
Frequently Asked Questions about 175Z7441:
Q: How does the Danfoss 175Z7441 Frequency Converter maintain performance when operating under changing load conditions?
A: It regulates current output with high efficiency, ensuring steady motor response. This stability reduces stress on connected systems and improves long-term reliability in industrial operations.
Q: What role does the external 24 V DC supply play in the 175Z7441 Frequency Converter?
A: It powers control and option cards independently, ensuring uninterrupted functionality. This feature also allows full operation of the Local Control Panel without mains power.
Q: How does the Danfoss 175Z7441 Frequency Converter handle power loss during maximum load operations?
A: The unit dissipates 426 watts of power loss under peak conditions. This controlled dissipation prevents thermal stress and safeguards the internal components during demanding use.
Q: What is the functional advantage of the detachable Local Control Panel in the 175Z7441 model?
A: It offers complete programming and monitoring with flexible installation up to three meters. The panel includes display, keys, and indicators for simplified operation and parameter handling.
Q: How does the Danfoss 175Z7441 Frequency Converter ensure safe operation when both DC and mains supply are connected?
A: A minimum 200-millisecond delay is required in parameter 111 for synchronization. This delay prevents tripping and ensures a smooth power transition between sources.
