dV/dt filter 3ph 400V 220-250kW copper. SE SEOP28-C25N4-CU Systeme Electric

dV/dt filter, brand Systeme Electric, series SystemeVar options, type SEOP28. Designed for VFD with rated power 250 kW and supply voltage 3Ph 400V. Filter type (installation relative to VFD): Output. It is connected to the output of the frequency converter to suppress voltage peaks and reduce the dv/dt transient voltage reflected by traveling waves in long cables, which allows reducing eddy current losses and motor noise, as well as protecting its insulation. Primarily used in situations where the supply voltage is too high, old motors require modernization, the insulation strength of constant frequency motors is low, or frequent braking and transmission are carried out using longer cables. Main conductor material: Copper. Rated current: 480 A. dV/dt level: ≤ 300 V/μs. Insulation class: F. Ambient operating temperature: from -25 to +55°C. Heat dissipation (conductor/core/total): 378.7/55.3/434 W. Cooling: Natural. Dielectric strength: AC 3000V 50 Hz for 60 s. Leakage current: ≤ 5 mA. Carrier frequency: 2kHz. Unshielded motor cable length: 150-450m. Shielded motor cable length: 100-230m. Noise level: ≤ 75dB. Protection degree: IP00. Max dimensions (WxDxH): 370x230x380 mm. Weight: 69 kg. Package dimensions (WxDxH): 466x356x528 mm. Gross weight: 76 kg. EAC marking (the product has undergone the necessary tests and meets safety requirements, so it can be freely sold in EAEU countries).
