Data Sheet High Voltage Multi-Range DC Power Supplies MR Series The MR Series high voltage multi-range DC power supplies deliver up to 5 kW of clean output power in a compact 2U form factor. These power supplies are suited for both bench use and automated test system applications requiring a wide range of voltage and current. For benchtop applications, this series offers an intuitive user interface for list mode programming and slew rate adjustments directly from the front panel. Operating software is provided for test sequence generation and data logging without the need to write source code. Integrators will benefit from fast command response times, excellent regulation, and low noise characteristics. In addition, this series supports USB, GPIB, LXI compliant LAN, and analog interfaces for remote control and programming. Up to 50 power supplies can be daisy-chained and controlled from one PC, or connect multiple power supplies in parallel for increased output power. The MR Series includes a built-in SAS (solar array simulator) function to generate I-V curves from the front panel. The optional SAS software allows users to simulate various weather conditions and consistently reproduce I-V curves while monitoring MPPT efficiency data. System Integration The MR Series offers many features for ATE system and integration applications.

High Voltage Multi-Range DC Power Supplies MR Series Flexible configuration and performance Multi-range operation Device protection 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 illustrated by the curves shown in the figure below. This flexibility means multi-range power supplies are capable of replacing multiple fixed range power supplies. To protect your DUT, the MR Series provides overvoltage (OVP), overcurrent (OCP),...

High Voltage Multi-Range DC Power Supplies MR Series Remote control and programming Adjustable slew rate and output timer Slew rate setting allows users to control the voltage and current slope (rise and fall times). The timer-controlled output can be set from 1 second to 255 hours. 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. Convenient front panel guided calibration Using a 5 ½ digit multimeter, voltage and current...

High Voltage Multi-Range DC Power Supplies MR Series Solar Array Simulation (SAS) Software Option Solar inverter designers need to verify their inverter is capable of delivering the maximum power available from solar modules. The I-V curve of solar cells can be influenced by various weather conditions such as a cloudy day. Combined with the SAS application software, MR users can easily simulate the I-V curve of different arrays under various irradiance conditions while measuring and validating the effectiveness of the inverter’s MPPT algorithm.
