3-Phase

Smooth power and heightened efficiency with 3-phase systems

On-systems is regularly designing, developing and supplying high quality 3-phase systems for a diverse range of clients. With our pioneering products, you’re guaranteed a more constant and reliable current. 3-phase power supplies allow for higher transmission at lower amperage, whilst the power of this system can be exemplified in two configurations; star connection (wye) or delta connection.

The key advantages of 3-phase power

The key difference between a single-phase and 3-phase power supply is that the 3-phase better accommodates high power loads, whilst other advantages include:

  • Copper Utilisation Reduction
  • Reduced security and safety risks
  • Increased efficiency
  • Facility to run high power loads
  • A smoother form of power
  • Helps extend a system or product’s lifespan

With a highly skilled team of UK designers, we have developed a range of dependable aerospace qualified, ARINC standard power supplies, whilst we remain agile and have grown to support partnerships in the defence, aerospace, rail, energy, marine and entertainment sectors.
