Description
Programmable DC Power Supply
The ML Series from Magna-Power Electronics has been engineered from the ground up to set a new standard in power density and performance. Leveraging advanced water-cooling technology, the 500 kW and 1,000 kW ML Series models achieves a nearly fourfold increase in power density compared to Magna-Power’s alternative air-cooled models. With the ability to connect in master-slave parallel configurations, the ML Series can reach power levels exceeding 10 MW. Built upon Magna-Power’s signature reliable current-fed power processing topology and innovative harmonic neutralization technology, the ML Series power supplies provide reliable and efficient power conversion with low harmonic distortion. Designed and manufactured in Flemington, New Jersey, the ML Series power supplies embody Magna-Power’s commitment to quality, reliability, and advanced engineering.
