The BK Precision MR50040 High Voltage Programmable Multi-Range DC Power Supply, 500V/40A, 5000W produces 5 kW of clean output power in a compact 2U form factor. This model is suited for both bench use and automated test system applications. For benchtop applications, this series offers an intuitive user interface for list mode programming and slew rate adjustments directly from the front panel. System integrators benefit from fast command response times, excellent regulation, and low noise characteristics. The MR50040 supports USB, GPIB, LXI compliant LAN, and analog interfaces for remote control and programming. The provided LabVIEW, IVI-C, and IVI.NET drivers further simplify system development. The MR Series provides a built-in web server that allows users to configure, control, and monitor the basic settings of the power supply, using a web browser on a computer connected to the same local area network. The list mode feature allows users to program a list of steps to the power supply's internal memory and execute them directly from the front panel. A total of 100 steps can be allocated to each internal memory location, for up to 10 locations. Each step setting includes voltage, current, duration and output status. List mode sequences can also be programmed remotely through the USB, RS232, GPIB, or LAN interfaces using SCPI commands or with the included application software. Traditional power supplies with rectangular output characteristics only deliver maximum output power at one voltage/current point. Multi-range functionality broadens the maximum power output from one point to a range. This flexibility means multi-range power supplies are capable of replacing multiple fixed range power supplies. For more power, models with the same rating can be connected in parallel and operate in master/slave mode. The RJ45 ports are used for communication between the master and slave(s). Once configured, the master will automatically search for and detect slave units and display the voltage and current of the complete system. The built-in SAS (solar array simulator) function enables users to generate PV (photovoltaic) I-V curves for testing solar inverters. Optional SAS software is available for simulating the I-V curve of different arrays under various weather and irradiance conditions.
