The MS Series utilizes the latest IGBT devices to drive down size and increase performance. The high frequency design delivers fast transient response and low output ripple. This performance coupled with Magna-Power's rugged current-fed power processing, enables confidence in even the most demanding applications.
All MS Series functions and features of are available and programmable from a variety of control methods, including:
Various programming interfaces are available, such as LXI TCP/IP Ethernet (+LXI), IEEE-488 GPIB (+GPIB), Edgeport USB, Accessory (+USB), RS485 Accessory (+RS485).
The following chart details the available standard MS Series models. The Current Maximum (Adc) column is separated by the available power levels. To determine the appropriate model, first select your output Voltage Maximum (Vdc) to find appropriate row. Next, select one desired Current Maximum from the row that contains your desired Voltage Maximum. Then, construct your model number according to the model ordering guide, above. Non-standard voltage and current configurations are available.
