MT Series: 150 kW & 250 kW High-Power Programmable DC Power Supplies
Scalable to 3,000 kW+ (3 MW) for Megawatt-Class Industrial, Aerospace, and Renewable Energy Test Systems.
Industrial Megawatt DC Power Processing with Built-In Grid Protection
The MT Series integrates high-frequency IGBT current-fed power conversion with heavy-duty floor-standing cabinet packaging. Built in Flemington, New Jersey, USA, MT Series units deliver single-cabinet power ratings of 150 kW and 250 kW, expanding seamlessly to over 3,000 kW+ via master-slave parallel operations.
Current-Fed IGBT Topology
Utilizes an inductive energy storage bus to naturally suppress arc discharge and load fault current transients. Delivers robust continuous operation across severe dynamic load environments without catastrophic switch failures.
Harmonic Neutralization
Standard embedded 12-pulse harmonic neutralizers on 250 kW models (with optional 24-pulse and 48-pulse external units) suppress 5th and 7th order harmonics, ensuring compliance with strict IEEE 519 grid power quality standards.
UID47 Master-Slave Control
Allows uniform high-power expansion up to 3,000 kW+. Paralleled stacks respond as a single integrated instrument driven by one central control loop without complex external programming logic.
MT Series Voltage & Current Output Configurations
Each MT Series power supply is manufactured with heavy-duty AC input breakers, digital front-panel controls, and isolated user I/O ports. Select from 49 standard models ranging from 32 Vdc up to 6000 Vdc.
