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.

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.

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.
