The requirement depends entirely on the specific machine's cycle and inertia.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan it operate on a standard 480V AC supply?\u003c\/strong\u003e\u003cbr\u003eIt is designed for 400V AC 3-phase input. A 480V supply would be too high and could damage the unit. A step-down transformer would be required to use this drive on a 480V system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is the key consideration for panel design when using this amplifier?\u003c\/strong\u003e\u003cbr\u003eHeat management is critical. You must ensure sufficient airflow (CFM) across the heat sink, proper clearances around the unit, and possibly additional cabinet cooling (fans, air conditioners) to maintain ambient temperature below 55°C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
