Product Description
Model X4C40075C is a high‑protection 3‑phase AC variable frequency drive of VACON X4 series (VACON is now part of Danfoss). Protection rating IP66 / NEMA 4X, wall‑mountable for on‑machine installation, withstands wash‑down, dust and humid harsh environments. Integrated local keypad. This model is discontinued by original manufacturer, available as new surplus, used or refurbished spare units. Equipped with built‑in dynamic braking, 9‑step on‑board sequencer (mini‑PLC logic), standard Modbus‑RTU communication. Supports V/F and open‑loop vector control for induction motors. ARCTIC cold‑climate operation mode is available. Mainly used for spare‑part replacement of legacy machinery.
