Prairie Machine / Rokion, a leader in electric vehicles for mining, faced a critical mission: ensuring a robust power source for their electric trucks. It was then that Premium PSU became the ideal strategic partner, taking reliability and power to the next level.
A leading manufacturer in the sector faced the challenge of improving the control of its motorized fans without compromising system stability or violating strict railway standards. By implementing the ODX-4500 inverter from Premium PSU, they optimized energy consumption, reduced mechanical failures, and ensured seamless integration with their existing infrastructure.
In an increasingly environmentally conscious world, leading companies are seeking innovative solutions to drive the transition towards a greener energy future. Iberdrola, globally recognized as one of the foremost companies in clean energy, grids, and storage, has partnered with us to develop a series of groundbreaking products that are redefining modern energy infrastructure.
Our collaboration with Iberdrola has resulted in the creation of two innovative products: the NP-0821 and NP-0822 power transformation chargers. These devices are designed to provide uninterrupted power supply and are instrumental in integrating new elements in low-voltage electrification, as well as adding new functionalities for the digitization of the power grid.

Demanding climatic environments require much more rigorous custom solutions to offer the customer the same reliability as other stable contexts. A factor such as extreme temperature is a stress factor for all components and this is one of the most common challenges at Premium PSU we face.
Generation of energy
The generation of electrical energy consists of transforming some kind of energy (nuclear, thermal, solar, among others) into electrical energy and is carried out in different stages. Power plants are the first actor in the electricity supply system. Electrical energy can be obtained from different sources, renewable or non-renewable energies. At the end of this article we show where power conversion systems meet in electrical energy in an infographic.
