AC to DC Constant Power Modules

Designed to power today’s most demanding wireless / IoT applications.

Very different from conventional switch-mode power supplies, the small and durable Bias Power BP constant power modules are a product designer’s dream. They have the widest input and temperature ranges of their class, making them able to tolerate virtually any power line or environmental condition. The output is equally strong & won’t hiccup or shut down when pushed, which means no need to over-specify/add headroom to get the performance that your circuit demands. This means you may be able to use a smaller, less costly power supply than you first thought. 

With no additional EFI/RFI suppression required in most designs, BP modules are the most cost-effective and complete, drop-in solution, ideal for today’s demanding control / wireless / IoT applications.  

  • 100% complete drop-in modular solution, no other engineering or sourcing required!
