DP Series II: Overview
Dual Polarity Tracking Output
Magna-Power Electronics DP Series II dual output tracking power supplies combine the best of DC power processing with multiprocessor embedded control to deliver dual polarity power systems. Available in systems ranging from 10 kW to 30 kW with voltage ratings as high as +/- 4000 Vdc. These tracking power supplies are current fed and are more tolerant to abusive loads than conventional switching power supplies. A combination of high and medium frequency power processing technologies improves response, shrinks package size, and reduces cost.
Motor and Ground Systems Testing
These high powered dual polarity systems are specifically targeted to ground systems operation and testing for both automotive and aircraft systems. The power supplies feature three output connections: positive output (+Vo), negative output (-Vo), and a common (ground). All tracking power supplies feature over-voltage protection (OVP) and over-current protection (OCP) as standard. These supplies are already being used around the world with applications such as:
- Brushless DC motor testing
- Aircraft ground support systems
- 270 Vdc DC Bus Testing (For example +/- 270 Vdc)
- Hybrid vehicle systems
- Water treatment
Unparalelled Control
TS SERIES power supplies can be configured through the front panel for different applications. The power supply can be programmed to have its control functions accessible from the front panel, rear connector, or through RS232, optional IEEE-488, or optional Ethernet communications. Sensing can be established at the output terminal of the power supply or through a rear terminal block for sensing at the load. An external interlock can be set to enable operation only when an external connection is made. Even calibration has been simplified with front panel access to calibration digital potentiometers.
TS SERIES power supplies incorporate an optically isolated feedback system. The result is that all user interface circuitry is referenced to earth ground -- not the negative terminal of the power supply. This enables users to connect external circuitry without concern of ground loops or voltage breakdown.
Designed for Safety
Magna-Power Electronics' tracking power supplies have extensive diagnostic functions -- all of which, when activated, take command to shut down the system. Diagnostic functions include phase loss, excessive thermal conditions, over voltage trip, over current trip, fuse clearing, and program line. Program line monitors externally applied analog set point signals to insure they are within the specified range. Upon a diagnostic fault condition, main power is disconnected and the diagnostic condition is latched into memory. Pressing the clear key clears the memory. All diagnostic functions can be monitored through a rear connector. Furthermore, control functions can also be set through the rear connector to allow simultaneous control of one or more tracking units.
Our trakcing power supplies have three levels of over voltage/current protection: shutdown of controlling insulated gate bipolar transistors (IGBT’s), disconnect of main power, and input fuses. After an over voltage/current trip condition, the supply must be reset.
