Datasheet

Magna-Power Electronics, a leader in high-power programmable DC power supplies, released their MT Series V power supply with a new, high power 250 kW module. This new fifth generation product now includes 65 models spread across independent 100 kW, 150 kW, and 250 kW modules, scalable into the megawatts through paralleling, with voltages from 16 Vdc to 4000 Vdc and currents from 24 Adc to 24000 Adc. The MT Series V features Magna-Power Electronics’ signature current-fed power processing, delivering additional power processing stages for increased system protection under abusive loads.

The newest 250 kW module integrates Magna-Power Electronics’ harmonic neutralizer, which suppresses families of AC harmonics by increasing the number of power phases—an important consideration for switch-mode power supplies in the hundreds of kilowatts. The harmonic neutralizer creates a 12-pulse AC waveform, minimizing harmonic distortion. The harmonic neutralizer eliminates families of harmonic components by multiplying the number of input phases with specially wound autotransformers, providing a cost effective solution to maintaining power quality at acceptable levels.

By designing a 250 kW module and integrating the harmonic neutralizer, the overall 250 kW system size was reduced by over 33%. In addition, the integrated harmonic neutralizer greatly reduces installation requirements, easing multi-module scalability.

The new MT Series V features identical controls and features as Magna-Power Electronics line of programmable DC power supplies. All the products come standard with RS-232 interface, programmable SCPI command set, isolated 37-pin I/O for PLC integration, and rotary front panel control, metering, and calibration. Furthermore, programming options such as LXI TCP/IP Ethernet (+LXI) and IEEE 488.2 GPIB (+GPIB) as well as performance options such as photovoltaic power profile emulation (+PPPE) and the recently released high slew rate output (+HS). Units are capable of master/slave parallel and series operation through the plug-and-play UID46 device.
