B+K Precision MR Series Multi-Range Programmable DC Power Supplies

Models B+K Precision MR3K160120, MR160120, MR25080, MR50040, MR100020

The B+K Precision MR series are 3 or 5 kW multi-ranging, single-output programmable DC power supplies. They offer up to 1000 V or 120 A in a compact 2U form factor and are well suited for both bench use and automated test system applications. The MR series offers multi-range functionality and provides users with added flexibility in the form of additional voltage and current combinations, capable of replacing multiple fixed-range power supplies. The MR series provides a wealth of features, such as a wide range of industry standard interfaces combined with excellent regulation and low noise characteristics.
