Active Front End — 240 kW, 480 V, built-in chassis
The VW3A7283 is a Schneider Electric active infeed converter (AIC) rated at 240 kW continuous power with a 480 V AC three-phase supply. It delivers 366 A continuous output current and draws 348 A line current at the rated voltage. This is a built-in unit — IP00, no enclosure — sized for integration into a panel or cabinet. The footprint is 950 mm high, 585 mm wide, 377 mm deep, and it requires 1000 cm² of air flow surface for forced convection cooling moving 1200 m³/h through the power circuit.
The AIC functions as the front-end rectifier for a common DC bus, providing low-harmonic input and energy regeneration capability. The 770 V DC output bus feeds downstream inverters; the 1.20× nominal current overload for 60 s (1.35× for 2 s) matches typical motor acceleration profiles. Thermal losses run 3560 W at full load — this is the heat the cabinet ventilation must extract. Operating ambient range is -10 to 45 °C without derating; above 45 °C derate 2 % per °C up to 60 °C. At altitudes above 1000 m derate 1 % per 100 m. Communication is via Modbus and CANopen through the onboard RJ45 and SUB-D 9 ports. The unit carries EN/IEC 61800-5-1 safety compliance, pollution degree 2, and environmental classification 3K3/3C2/3S2 per IEC 60721-3-3.
Obsolete — sourcing through independent channels
Schneider Electric lists the VW3A7283 as obsolete. The unit is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.
