1. Compared with traditional passive filters, HFR series products are smaller in size and have stronger harmonic suppression capability
2. When the harmonic filter is connected in front of the converter, the total harmonic current after filtering is less than 10% of fundamental current at full load
3. The efficiency can be greater than 98%, and the power can be up to 250kW. Passive harmonic filters provide cost-effective, stable and reliable harmonic solutions
4. It is easy to be installed in cabinets
5. This series of filters has been carefully matched with brand converters, and suitable for a variety of motor control methods to ensure stable operation of the system without any effects on the power grid
1. Rated Voltage: AC 380 ~ 480V
2. Rated Frequency: 50Hz
3. Overload Capacity: 1.5 × rated current, 60s
4. Insulation Class: overvoltage category Ⅲ complies with EN61800-5-1
5. Full load efficiency: >98%
6. Cooling Method: AN
7. Harmonic filtering effect: Under full load conditions, the total harmonic current distortion rate THDi at the filter input is < 10% (background voltage THDu < 2%, ratio of electrical network rated power to load power > 66)
8. Ambient Temperature (Operating): under full load, -25?+50℃
9. Storage Temperature: -25 ~ +65℃
10. Working Altitude: 0 ~ 2000m
11. Relative Humidity: 0 ~ 95% without condensation
12. No-load current: less than 25% of the rated current
IEEE519 GB/T14549
1. DHF harmonic filters are matched with converters, and can only be installed at the incoming power line of the uncontrollable rectifier converter
2. The power of the filter should match that of the converter as much as possible when used. In this case, the best filtering effect can be obtained. When a larger-power filter is used with a smaller-power converter, the filtering effect will be affected negatively
3. The reactor in the filter is a heating device. When installing, make sure to keep at least 100mm of space around the filter
4. During installation, follow the wiring instructions in the circuit diagram and connect a reliable ground wire
5. When the operating environment such as altitude and power quality exceeds the technical requirements, please consult the manufacturer
