The MR Series of high voltage multi-range DC power supplies include 250 V, 500 V, and 1000 V models producing 5 kW of clean output power in a compact 2U form factor. 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 30 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.

Flexible configuration and performance
Multi-range 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.
List mode

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.
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.
Master/Slave operation

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.
Multi-unit control

Up to 30 units can be daisy chained and controlled from one master unit through the USB, GPIB, or LAN interface.
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.
Analog programming and monitoring

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).
Web server interface

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.
Socket and Telnet interface
The power supply 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 1/2 digit multimeter, voltage and current parameters can be conveniently calibrated from the front panel via the calibration menu.
