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.
The new equipment boasts advanced algorithms that facilitate the monitoring and control of power supply assets in the transformation centers, all while ensuring strict compliance with the client’s cybersecurity requirements. This equips the network with greater adaptability to address any power supply issues that may arise.
The key characteristics of these devices include:
Uninterruptible power supply system for 48V LiFePO4 batteries
2 outputs of 500W (750W for 10s) and 250W (500W for 10s) isolated at 10kV from each other
2 or 3-state battery charging
Local monitoring with 3 LEDs
Remote monitoring with 4 alarm relays
Configurable charging parameters
Alarm signaling through potential free relays
2 Ethernet ports for local and remote configuration and monitoring
1 CAN port for communication with BMS
Integrated web server
Battery connection via solid-state relay
10kVac input-output isolation
Uninterruptible power supply system for multiple types of 12V batteries (lead acid, lithium, etc.)
2 or 3-state battery charging
1 output of 12V 200W (400W for 10s) and 2 independent 48V outputs for maneuver (200W / 300W for 10s) and control (60W) with a peak of 400W for 10s
Local monitoring with 3 LEDs
Remote monitoring with 4 alarm relays
Configurable charging parameters
Alarm signaling via potential free relays
2 Ethernet ports for configuration and remote monitoring
1 CAN port for communication with BMS
Integrated web server
Battery connection via solid-state relay
2kVac input-output isolation
The development of these innovative power transformation chargers signifies our commitment to pushing the boundaries of technological advancement in the field of sustainable energy and power grid management. By delivering solutions that cater to the evolving needs of our clients, we continue to pave the way for a more efficient and secure power infrastructure.
These case studies highlight how Premium PSU’s Variable Frequency Drive TDS-3300 and TDX-3300, successfully addressed the specific power conversion needs of two different train manufacturers, resulting in customer satisfaction, projected production growth, and expansion into new railway projects.

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.
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.
This article intends to resume the most important requirements that apply for power supply devices when considered as a component in railway applications. Although there are several standards to take into consideration when installing electronic equipment in trams and trains, we will be focusing on the EN50155.
In this new article, we want to introduce how our newest DC/DC converter CBS-10K works with a “Start-up diesel engine” application in the hybrid trains. The CBS-10K has been designed under rolling stock standards and is the perfect complement to start the diesel engine in diesel-electric hybrid trains.
