Selection Checklist + RFQ

Choose voltage/current model matching your source specifications (80V to 2000V, 20A to 510A).
Confirm total power requirement ≤ 5kW, 10kW, or 15kW; note derating to 3/6/9kW at 208V AC input.
Verify AC supply voltage (208-480V AC three-phase) and plan for proper grid compliance regarding energy recovery.
Select required interfaces: built-in analog/USB/Ethernet plus any optional industrial bus modules (CAN, Profibus, ProfiNet, EtherCAT, etc.).
For master-slave operation, specify total system power and number of units; ensure all units have same voltage rating.
Plan for installation in a closed 19" rack with adequate cooling and lockable doors.
