PM modular series - PMAE cabinet

PMAE series modular converter is designed for on-grid application, the product adopts pre-assembled standard cabinet design, which consists of PMA standard power module, electrical distribution, 10-inch smart screen, EPO switch, etc. It supports flexible increase and decrease, the power level of a single cabinet covers 50kW~630kW, and can be extended by up to 4 cabinets, realizing a single system of 1MW. Supporting single and multi-branch input technology, power modules and electrical distribution can be flexibly configured on demand to reduce construction costs and quickly achieve AC / DC bidirectional energy conversion.

Product Highlights

Highly efficient and intelligent

Leading multi-machine parallel connection and parallel cabinet application technology, with active resonance suppression, parallel communication single line fault normal operation.

Leading equalization and loop current suppression application technology, with low-frequency, high-frequency loop current suppression, self-equalization control.

Convenient and reliable

The 10 industrial screen with integrated EMS function supports local remote operation and maintenance

Equipped with an emergency stop switch for safer system operation.

Simple and flexible

The power of a single cabinet can cover 60-630kw, supporting a maximum of 4 cabinets connected in parallel, easily realizing MW-level capacity expansion.

Pluggable replacement repair can be redundant configuration, does not affect the system operation.
