About Sinepower
Power electronics engineered in Portugal
Sinepower builds power equipment for operations that cannot afford downtime — aircraft on the stand, ships at berth, fleets on charge. The company is 20+ years old and our engineering team carries over 40 years of power electronics behind it, which is why our units are specified by airlines, air forces, ports and distributors across four continents.
Every unit is manufactured under an ISO 9001 quality system certified by TÜV Rheinland, and supported by the same engineers who designed it.

Our focus
Built for demanding industries
Sinepower supplies power equipment to industries that work at the edge of tolerance. Our team covers civil and military aviation, the maritime industry and electric vehicle charging — from catalogue units to equipment developed to your specification.
400 Hz solid state ground power units and 28 VDC supplies for civil and military aircraft, fixed or mobile, from 30 kVA to 180 kVA.
Ship-to-shore static frequency converters for cold ironing and Onshore Power Supply (OPS). Vessels shut down their auxiliary engines at berth and draw clean 50/60 Hz power from the quay instead.
DC charging equipment for electric fleets, depots and public charging networks.
Equipment developed to your specification, from concept and prototype through to a certified production unit.

Our clients
A trusted power partner worldwide
During our service, we have learned a lot of the short comings on many different GPUs. This led us to find a company that will both acknowledge these issues, and also, work with a company with same customer-first mentality. After rigorous research and testing, we are thrilled to announce our partnership with Sinepower. We look forward to our future together and excited to introduce the product to the North American business aviation market.
