This series 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. 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.

High Voltage Multi-Range DC Power Supplies MR Series www.bkprecision.com Flexible configuration and performance Device protection To protect your DUT, the MR Series provides overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OTP) protection. A fault will trigger an alarm and disable the output. Similarly, with constant voltage-to-constant current (CV-to-CC) or constant current-to-constant voltage (CC-to-CV) foldback protection mode activated, the output will be disabled if load changes force the supply to transition between the two operating modes. Up to 50 units can be daisy chained and controlled from one master unit through the USB, GPIB, or LAN interface. Multi-unit control This 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. List mode 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. Master/Slave operation 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.

Save and recall list files to/from the PC. Application software and integration Using a 5 ½ digit multimeter, voltage and current parameters can be conveniently calibrated from the front panel via the calibration menu. Convenient front panel guided calibrationThe 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. Web server interface The power supply can be configured for Socket or Telnet connections through the LAN (Ethernet) and controlled using SCPI commands. Socket and Telnet interface 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. Adjustable slew rate and output timer The galvanically isolated analog interface can be used to monitor voltage, current, regulation mode (CV or CC), or to indicate fault conditions. In addition to front panel and PC interface control, the MR Series can be controlled from zero to full scale by an external voltage signal or resistor (0 to 5 V / 5 kΩ or 0 to 10 V / 10 kΩ selectable).

High Voltage Multi-Range DC Power Supplies MR Series www.bkprecision.com 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.

The MR power supply outputs points on the I-V curve in 1 ms intervals to test the inverter’s MPPT efficiency. Automatically generate PV and I-V curves by specifying open circuit voltage (Voc), short circuit current (Isc), maximum power voltage (Vmp), and maximum power current (Imp) along with temperature coefficient (ß). PV simulation curve Generate custom I-V curves using Excel or Notepad to create a 4,096 point voltage and current table. Use the SAS software to download the I-V curve table to the power supply’s internal memory for output. Shadow Simulation Use the shadow simulation mode to test solar arrays under different weather conditions. Adjust cloud intensity, cloud direction, and timing parameters. Resulting PV and I-V curves are automatically generated along with MPPT efficiency data. Free Trial Try SAS software free for 30 days. Visit bkprecision.com to learn more.
