Bronson MII 4500

(0 review)

The Bronson MII 4500 is a high-load isolation transformer with step-up capability — engineered for large vessels, industrial facilities and professional productions that demand continuous safe isolated power at scale.

Max. 4500W / Continuous 3600W — sustains large-scale isolated power distribution across multiple high-draw systems
Step-up + galvanic isolation in one — 110V or 230V in, fully isolated 230V out
Large vessel shore power — isolates entire onboard electrical systems from harbour mains safely and reliably
Industrial-grade construction — built for permanent installation and continuous operation without performance degradation
Ideal for — large ships and yachts, industrial production lines, major stage productions and data centres
