Case studies by industry
At Premium PSU we have worked with projects from different types of sectors or industries. We highlight four main areas: Transport and Rail, High Tech, Energy and Extreme Environments.
DC/AC Inverters for emergency railway HVAC systems
Power supply for rolling stock can be critical, especially in emergency-related applications such as HVAC systems, where a ventilation circuit is needed for safety and passenger comfort reasons when a train loses its main power source (catenary…
Power solutions that work under extreme temperature conditions
At Premium PSU, we develop and manufacture power supplies for all kinds of applications and every project is a challenge for us. Sending one of our products to the stratosphere at 32.000 meters and -57ºC confirms the high reliability of…
Feeding an AGV industrial robot with a 3ph inverter
Industrial robots are widely used in industrial automation environments and need to be powered by 3-phase 3x400Vac industrial voltage. This is not a problem when using devices in static locations, however, this changes when the customer…
High Voltage input 3ph inverter for demanding railway HVAC systems
Rolling stock railway systems are usually fed from secured battery voltage (typically: 24V, 36V, 72V or 110V) or from the AC voltage supplied by a high-power auxiliary converter. However, when it is time to refurbish an old train, many peculiarities…
