MR Series High Voltage Multi-Range DC Power Supplies

The MR Series high voltage multi-range DC power supplies provide up to 5 kW of clean output power in a compact 2U form factor, making them ideal for bench use and automated test systems. This series offers exceptional flexibility with wide-ranging voltage and current capabilities, effectively replacing multiple fixed-range power supplies.

For benchtop applications, the MR Series features an intuitive front panel interface that allows for list mode programming and slew rate adjustments. System integrators benefit from fast command response times, excellent regulation, and low noise performance, making these power supplies well-suited for automated systems. The series also supports a wide range of interfaces, including USB, GPIB, LXI-compliant LAN, and analog control for remote operation and system integration.

In addition, the MR Series includes a built-in Solar Array Simulator (SAS) function, enabling the generation of photovoltaic (PV) I-V curves for testing solar inverters. An optional SAS software package is available to simulate the I-V curves of various solar arrays under different weather and irradiance conditions.
