BK Precision MR3K160120 – 160V, 120A, 3 kW High Voltage Multi-Range DC Power Supply
Max output voltage – 160 V
Max output current – 120 A
Max output power – 3000 W
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.

MR Series Features
Flexible Configuration and Performance
Multi-range operation – multi-range functionality broadens the max power output from one point to a range; capable of replacing multiple fixed range power supplies
List mode – allows users to program a list of steps to the power supply’s internal memory and execute them directly from the front panel; 100 steps to each internal memory locations (10)
Device protection – to protect your DUT, the MR Series provides OVP, OCP, OPP, and OTP protection; the output is disabled when a fault is triggered, the same with CV-to-CC and CC-to-CV foldback protection mode is activated
Master/Slave operation – for more power, models with the same rating can be connected in parallel and operate in master/slave mode; RJ45 ports used for communications
Multi-unit control – up to 50 units can be daisy chained and controlled from one master unit through the USB, GPIB, or LAN interface
Remote Control and Programming
Adjustable slew rates and output timer – allows user to control rise and fall times; timer-controlled output can be set from 1 second to 255 hours
Analog programming and monitoring – galvanically isolated analog interface can be used to monitor voltage, current, regulation mode (CV or CC), or to indicate fault conditions
Web server interface – built-in web server to configure, control, and monitor basic settings on the power supply, using a web browser on a computer connected to same local area network
Socket and Telnet interface – can be configured for Socket or Telnet connections through the LAN (Ethernet) and controlled using SCPI commands
Convenient front panel guided calibration – using a 5.5 digit multimeter, voltage and current parameters can be conveniently calibrated from the front panel via the calibration menu
Application software and integration
PC software – provided for front panel emulation, generating and executing test sequences, or logging measurement data without the need to write source code
Log voltage, current, and power values as well as time stamp, CV/CC, and output status
Save and load list files to/from the power supply’s internal memory
Create an unlimited number of external list files to be executed from PC memory; save and recall list files to/from the PC
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.
SAS Software Option Features
PV simulation and shadow simulation modes
Variety of input parameters (Voc, Isc, Vmp, Imp, and temperature coefficient)
Monitors and logs real-time voltage, current, power, MPPT efficiency, and average MPPT efficiency
Simulate I-V curve under different weather conditions during a day
User-definable irradiance profile
Generate a custom I-V curve with up to 4,096 data points
Test to EN50530, NB/T32004, Sandia lab standards
