Medical Grade Isolation Transformers

Bridgeport Magnetics offers both standard and custom designs of 60 Hz and 50/60 Hz isolation transformers for medical applications up to 5,000 VA with single, dual or quad primary voltages and customer specified secondary voltages.

We can also provide isolation transformers inside NEMA style enclosures to your exact specifications.
Our ISO-PUCK family of enclosed and corded medical grade isolation transformers with plugs and receptacles are available up to 3000VA for 60Hz and 2500VA for 50/60Hz.

Benefits of Using Certified Transformers
Using a certified medical grade isolation transformer in your product reduces your cost and time for safety testing which helps you bring your product to the market much sooner.

  • Power Ratings:
    Up to 5,000 VA single phase and 15,000 VA three-phase.
