Wide-Range Output with Auto-Ranging

Compared with conventional DC power supplies with fixed output ranges, the MP Series delivers full rated power across a wide range of voltage and current combinations.

A single MP Series power supply can cover an output range equivalent to three conventional power supplies. For example, a 200 V / 210 A / 15 kW MP Series unit can deliver 200 V / 75 A or 71.4 V / 210 A, while providing the full 15 kW rated power at any voltage point between 71.4 V and 200 V.

This wide-range, constant-power output capability significantly enhances power supply flexibility while reducing system complexity, equipment footprint, and overall setup costs.

Powerful Arbitrary Waveform Generator

The MP Series features a built-in multi-function waveform generator, enabling users to easily create and combine triangular, rectangular, trapezoidal, sine, step, and other waveforms.

Waveforms can be applied to either output voltage or current, providing powerful and flexible programmable testing capabilities for a wide range of test scenarios.

Fast Dynamic Response

Featuring advanced multi-loop composite control technology, the MP Series delivers exceptional dynamic performance.

During instantaneous loading, voltage drop is less than 1%, while unloading produces virtually no voltage overshoot. The dynamic response time is less than 2 ms, ensuring fast and stable output under rapidly changing load conditions.
