dV/dt filter 3ph 400V 55kW alum. SE SEOP28-D55N4-AL Systeme Electric

dV/dt filter, Systeme Electric brand, SystemeVar options series, type SEOP28. Designed for VFD with rated power 55 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 helps reduce eddy current losses and motor noise, as well as protect its insulation. Mainly used in situations where the supply voltage is too high, old motors require upgrading, insulation strength of constant frequency motors is low, or frequent braking and transmission are carried out using longer cables. Main conductor material: Aluminum. Rated current: 120 A. dV/dt level: ≤ 300 V/μs. Insulation class: F. Ambient operating temperature: from -25 to +55°C. Heat dissipation (conductor/core/total): 127.9/23.9/151.8 W. Cooling: Natural. Dielectric strength: AC 3000V 50 Hz for 60 s. Leakage current: ≤ 5 mA. Carrier frequency: 4kHz. Unshielded motor cable length: 150-450m. Shielded motor cable length: 100-230m. Noise level: ≤ 75dB. Protection degree: IP00. Max. dimensions (WxDxH): 225x175x230 mm. Weight: 20 kg. Package dimensions (WxDxH): 320x270x330 mm. Gross weight: 24 kg. EAC marking (product has passed necessary tests and meets safety requirements, so it can be freely sold in EAEU countries).
