mPower 300 Series 3 kW Programmable DC Power Supply

Marway’s lab-quality mPower 300 Series dc power supply product line includes many capabilities usually found only in systems costing much more. This compact 1U package features auto-ranging output, multiple communications protocols, the ability to parallel up to 10 units, a graphical display, and more.

Powerful capabilities

  • Five models offering up to 750 Vdc at 12 amps, or up to 100 amps at 80 Vdc.
  • Parallel output connectivity of up to 10 units to create a total power output of up to 30 kW.
  • Operate in constant voltage, current, or power mode.
  • Autoranging power output enables the system to deliver 100% power over a wide range of voltage and current.
  • Active power factor correction of input power.
  • USB, Ethernet, and analog remote control interfaces.
  • USB for remote control through Windows®, LabView®, and your own custom scripts.
  • Ethernet for remote control using your own custom scripting.
  • Analog Interface for remote control and monitoring of key operational parameters of the system using a PLC or your own custom control circuitry.
  • Output Share Bus regulates voltage and current load for up to 10 parallel connected units.
  • Output Voltage Sense Bus monitors voltage at the load, instead of the output terminals, to compensate for minor losses in output cables up to 5% of the system’s rated dc voltage.
  • Graphical display user interface with multiple buttons, and two rotary controls (which speed up data entry) allows for complete configuration, control, and monitoring.
  • Safety features including user interface lockout and quick discharge circuitry. Built-in alerts for over voltage, current, power, and temperature.
