MT series large power cabinet programmable DC power supplies, expandable up to multiple megawatts. This series of products uses the same technology and control methods as other products in the MagnaDC programmable power supply product line, but has larger power models: 100kW, 150kW and 250kW specifications. The MT series based on high-frequency IGBT is one of the largest single-power standard programmable DC power supply products on the market, and the number of switching elements is minimized compared to small-power model products. The UID47 device can be used to expand the megawatt power level, which provides master-slave control: a master power supply controls other slave power supplies to realize true system-level operation control. All MT series products are equipped with rated full-power AC input circuit breakers as an additional safety protection measure. The 250kW model is equipped with a built-in 12-pulse harmonic neutralizer to ensure lower THD (total harmonic distortion). Externally attached 500kW 24-pulse or 1,000kW 48-pulse harmonic neutralizers can provide better AC waveforms, which are specially designed and manufactured by MagnaElettronica for its MT series products.
