Magna-Power Electronics Announces Dual Polarity Tracking Power Supplies Up to 900kW

Magna-Power Electronics announced its dual output tracking power supplies that are said to combine the best of dc power processing with multiprocessor embedded control to deliver dual polarity power systems.

Available in systems ranging from 6.6 to 900kW with voltage ratings as high as +/- 3000Vdc. These tracking power supplies are current fed and are said to be more tolerant to abusive loads than conventional switching power supplies. A combination of high and medium frequency power processing technologies is said to improve response, shrink package size, and reduce cost.

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; and water treatment.

A wide range of programmability options are available for software control: RS232, GPIB, Ethernet, USB. Additionally, the systems can be programmed using external I/O isolated to earth-ground and reference signals, enabling maximum system integration.
