Oscilloscope-like UI! Equipped with a convenient Sweep mode! High voltage 1000V external I/O equipped!
The high-end large-capacity DC electronic load "QL-D Series" adopts an oscilloscope-like UI and a high-speed current control circuit, enhancing usability and the fundamental performance of electronic loads, building on the positive feedback received for conventional electronic loads. It evolves the basic specifications, performance, and concept of the previous 34000A series, offering features such as Sweep functionality through various load modes and MPPT functionality as an option, catering to diverse needs with a variety of functions. It is available in increments of 5kW up to 25kW and can be expanded to 150kW with a maximum of 6 units in parallel. The compact design achieves a height of 5U (for the 5kW model) in a 19-inch rack size.
