ACHIEVES HIGH POWER UP TO 120 kW IN A SINGLE SMART RACK

  • Output voltage: Up to 1000 V
  • Output current: Up to 6000 A
  • Output power: Up to 120 kW
  • Space-saving smart rack design with 19.3-inch width

High power programmable DC power supply

The REM series is a high-power programmable DC power supply capable of delivering up to 120 kW safely and reliably. Its modular design allows for flexible configuration and scalability, enabling efficient capacity planning and maximizing return on investment.
The unit features a clear LCD panel that displays total output current and comes equipped with comprehensive protection circuits, making it an ideal solution for demanding R&D and industrial applications.

FEATURES AND BENEFITS

  • Space-saving Design: Compact cabinet width of just 19.3-inch (490 mm).
  • High Power Density: Delivers up to 120 kW in a single rack (expandable up to 360 kW).
  • Energy Efficient: High efficiency up to 90% reduces power consumption. An optional power factor correction circuit contributes to minimizing power distribution infrastructure requirements.

APPLICATIONS

  •  EV / HEV / Automotive Components

    Evaluation testing of inverters, DC/DC converters, DC motors, relays, and harnesses.

  •  Solar Energy and Photovoltaics

    Evaluation testing of PV inverters (power conditioners) and junction boxes.

  •  General Industrial and Research

    Rechargeable battery charging, electrolysis (including hydrogen production), and evaluation of fuses, connectors, and lamps.

  • All the lineup models are to be housed in a single dedicated 19-inch rack. (See page the datasheet for dimensions and other information.)
  • Extendable up to 360 kW, the device is suitable for larger power operations.
    However, note the following points for extension:
    • Extension is allowed only with the same model.
    • You must be responsible for wiring or other operations for an extension.
    • You might have to allocate space for mounting additional racks. Prior to the extension, please contact our sales staff concerning the total number of racks.
    • Both input and output are made for each rack regardless of the number of racks used. A breaker is mounted on each rack when the –LBr option is selected. Breakers cannot be integrated.
