Improving consistency and performance while lowering overall costs remains the challenge when it comes to power conversion products relating to Ground Power Applications.

You’re overpaying for yesterday’s standardized technology that is limited in its input capability and lacks the versatility you need to continue to lead and be competitive in this marketplace.

Allstar Magnetics offers your business the solution to these problems through the uniqueness of our multi-tab GPU rectifier transformer’s.

Rather than requiring several transformer designs each built for limited/specific power input, our innovative transformers are specifically designed for a maximum of ground power applications. Equipped with multiple tabs that provide versatility in a single unit, these transformers are capable of meeting almost any range of variable input power requirements in a single unit. The savings in both cost and inventory are significant as this solution eliminates out the need to purchase multiple units for the same functions.

Simply put, we are experts when it comes to ground power applications, and specifically we understand the importance of flexibility & quality when it comes to transformers.

For more than 25 years, Allstar Magnetics has been proud to be your partner by providing you with precision power transformers and power conversions with product innovations and advancements that are truly unmatched in the industry.

In addition to the cost-saving benefits of our Design & Engineering, our On-Demand just-in-time distribution gives you peace of mind in managing inventory more effectively though us. Traditionally, your components are made to order which involves lengthy lead times as well as high carrying cost.
