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.
