dV/dt Filter 3ph 400V 280kW Cu SE SEOP28-C28N4-CU Systeme Electric

dV/dt filter, Systeme Electric brand, SystemeVar options series, type SEOP28. Designed for VFD, rated power 280 kW and supply voltage 3Ph 400V. Filter type (installation relative to VFD): Output. Connects to the frequency converter output to suppress voltage peaks and reduce dv/dt transient voltage reflected by traveling waves in long cables, which reduces eddy current losses and motor noise, as well as protects its insulation. Mainly used in situations where the supply voltage is too high, old motors require modernization, constant frequency motor insulation strength is low, frequent braking and transmission are carried out using longer cables. Main conductor material: Copper. Rated current: 540 A. dV/dt level: ≤ 300 V/µs. Insulation class: F. Operating ambient temperature: from -25 to +55°C. Heat dissipation (conductor/core/total): 380.5/52.3/432.8 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: 75 kg. Package dimensions (WxDxH): 466x356x528 mm. Gross weight: 82 kg. EAC marking (the product has passed the necessary tests and meets safety requirements, so it can be freely sold in EAEU countries).
