MagnaDC - Model MT Series -Programmable DC Power Supplies
Magna-Power Electronics MT Series uses the same reliable current-fed power processing technology and controls as the rest of the MagnaDC programmable power supply product line, but with larger high-power modules: individual 150 kW and 250 kW power supplies. The high-frequency IGBT-based MT Series units are among the largest standard switched-mode power supplies on the market, minimizing the number of switching components when comparing to smaller module sizes. Scaling in the multi-megawatts is accomplished using the UID47 device, which provides master-slave control: one power supply takes command over the remaining units, for true system operation. As an added safety measure, all MT Series units include an input AC breaker rated for full power.
250 kW modules come standard with an embedded 12-pulse harmonic neutralizer, ensuring low total harmonic distortion (THD). Even higher quality AC waveforms are available with an external additional 500 kW 24-pulse or 1000 kW 48-pulse harmonic neutralizers, designed and manufactured exclusively by Magna-Power for its MT Series products.
