Product details

What this output reactor does on your drive line

Rated inductance is 0.18 mH, with a voltage drop of 12.8% at rated conditions — that drop matters for motor torque at full load, so factor it into your drive sizing. The 196 A maximum is the thermal limit at 40 °C ambient; the iron-core loss of 22 W and coil loss of 582 W add up to 604 W total heat that has to leave the enclosure — IP00 means no housing, so it needs panel airflow or forced ventilation.

Footprint is 0.41 m wide by 0.38 m tall by 0.22 m deep — this is a panel-mount component, not DIN-rail; plan for bolt-down on a backplate with clearance for the flat-type terminals on the main circuit connections. Thermal class H insulation (180 °C continuous) means it handles the reflected-wave stress from IGBT drives without derating for most PWM carrier frequencies up to the rated 1400 Hz.
