Brake resistor for inverters ATV930D22M3, ATV930D75N4, ATV950D75N4, ATV950D75N4E. Reference values for a heavy braking cycle (lifting applications). Power 32 kW, protection class IP23, resistance 5 Ω at 20 °C. Supply voltage 200-240 V or 380-480 V, 50/60 Hz. Load factor for resistors: The value of the average power that can be dissipated from the resistor into the housing at 50 °C. Designed for a load factor during braking that corresponds to the majority of common applications. High overload: 54 seconds of braking at a braking torque of 1 ton and 6 seconds of braking at a braking torque of 1.65 tons for a cycle of 120 seconds. Required quantity per inverter: 1.
