Product details

It handles a maximum AC current of 224 A and a peak current of 280 A, with a rated inductance of 0.13 mH and a relative inductive voltage drop of 4% at rated current. That 4% drop is the key spec for sizing — it tells you the impedance the choke adds to the DC link or line side, which governs how much it limits di/dt and reduces harmonic distortion on the converter input.

This is an open-frame (IP00) choke — no enclosure, so it needs to live inside a panel or cabinet where it's protected from dust and contact. Mounting dimensions are 0.27 m wide by 0.248 m tall by 0.187 m deep. The main circuit connections are flat-type terminals, which means you'll need either flat busbars or ring-tongue cable lugs sized for the 224 A continuous current. Thermal class H insulation (180°C rated) means the coil can run hot without degrading the magnet wire — important when the choke is packed into a cabinet with other heat sources.

Total power loss breaks down to 174 W in the coil and 80 W in the iron core, so you're looking at about 254 W of heat to manage inside the panel. That's not trivial — factor it into your cabinet cooling calculation, especially if the drive and choke share the same enclosure. The DC-rated current is 274.5 A, which is higher than the AC rating; that's typical for a choke where the DC current in the link is the limiting factor for saturation, while the AC rating governs the line-side harmonic performance.
