4 Quadrant Power Supply and Dynamometer Controller

8960-P

Description

The 4-Quadrant Power Supply and Dynamometer Controller is a highly versatile USB peripheral designed to be used in the Electric Power Technology Training Systems. Two operating modes are available: Power Supply and Dynamometer. To implement the Dynamometer Controller mode, a Dynamometer Motor is required. A wide variety of user-selectable functions is available in each operating mode.

In the Power Supply mode, the unit becomes a four-quadrant power supply that can act as a dc voltage source, dc current source, ac power source, etc. In the Dynamometer Controller mode, the unit becomes a four-quadrant dynamometer that can act as either a fully configurable brake (i.e., a mechanical load) or a fully configurable prime mover (i.e., a motor drive).

In each operating mode, key parameters related to the selected function are displayed. Voltage, current, electrical power, and energy are displayed in the Power Supply mode, while speed, torque, mechanical power, and energy are displayed in the Dynamometer Controller mode. Optional functions, such as a small wind-turbine emulator, a hydraulic turbine emulator, a solar panel emulator, battery chargers, an SDK (Software Development Kit) etc., can be added to the standard functions to further enhance the training possibilities of the 4 Quadrant Power Supply and Dynamometer Controller.

Two modes are available to control the function which the 4 Quadrant Power Supply and Dynamometer Controller performs: Manual and Computer-Based.

In the Manual control mode, the unit is stand-alone, and the function performed is selected, set, and monitored using front-panel mounted controls and display. This mode provides access to all basic functions. In the Computer-Based control mode, the function performed by the module is selected, set, and monitored using the LVDAC-EMS software. In this mode, communication between the 4 Quadrant Power Supply and Dynamometer Controller and the host computer running the LVDAC-EMS software is achieved through a USB connection. This mode provides access to all basic functions, as well as to additional advanced functions.

The 4 Quadrant Power Supply and Dynamometer Controller is powered from a standard wall receptacle via a line cord that connects to the front panel. The module helps energy conservation by returning the mechanical or electrical energy it receives to the ac power network while maintaining a unity power factor.

A USB port connector mounted on the front panel allows the 4 Quadrant Power Supply and Dynamometer Controller to be connected to a USB port of the computer running the LVDAC-EMS software (USB cable included with the module). A main power connector mounted on the front panel is used to connect the module to a standard wall receptacle using a conventional line cord (included with the module). All inputs and outputs of the 4 Quadrant Power Supply and Dynamometer Controller are protected against improper connections and overvoltage/overcurrent conditions.
