Best for / Not for

Best for: High-power battery discharge testing, solar panel MPP profiling, automotive 12V/24V/48V/400V system validation, power supply burn-in testing, and large-scale industrial test systems requiring energy efficiency and scalable parallel operation.
Not for: AC load applications, series connection of DC inputs (not permitted), operation without proper energy recovery grid compliance, or environments without adequate rack cooling.

Selection Checklist + RFQ

Choose voltage/current model matching your source specifications (80V to 1500V, 6A to 120A).
Confirm total power requirement ≤ 1500W or 3000W; note derating to 1200W/1500W at 110-127V AC input.
Verify AC supply voltage (110-240V AC single 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.
