Specifications Manufacturer: Stromag Type: CFU 220/380V Part Number: 947-07490 Function: Rectifier / Power Supply Unit Input Voltage: 220/380V AC Label Info Serial Number: 4341 Year of Manufacture: 2016 Application This power supply unit is commonly used in applications requiring controlled DC voltage, such as motor braking systems, conveyor controls, and various automation tasks where electromagnetic components are deployed. Country of Origin This product is made in France. CO2 Impact Opting for this reconditioned unit instead of a new one prevents the emission of approximately 20.0 kg of CO2. This saving is comparable to driving a car for 100 kilometers. Availability This item is in stock and ready for immediate dispatch. Order now from profideals for expert support and fast delivery. FAQ What is the typical output DC voltage for this CFU 220/380V unit? As a half-wave rectifier, the output DC voltage is approximately 0.45 times the input AC voltage. For a 220V AC input, the output would be around 99V DC, and for a 380V AC input, it would be around 171V DC, which are standard voltages for many industrial brakes. Is this rectifier suitable for continuous duty applications? Yes, Stromag rectifiers like the CFU series are specifically designed for continuous industrial operation, such as holding a brake in the open position or keeping a clutch engaged for extended periods. What is the purpose of the three cable glands on the enclosure? Typically for a unit like this, two glands are used for the AC power input (e.g., Line 1 and Line 2/Neutral), and the third gland is for the DC output (+ and -) that connects to the brake or clutch coil.
