Bronson MII 500

The Bronson MII 500 is a versatile isolation transformer with step-up capability — the reliable choice for workshops, marine applications and lab environments that need safe isolated 230V power from any mains voltage.

Max. 500W / Continuous 400W — powers workshop instruments, marine electronics and audio equipment safely
Step-up + galvanic isolation in one — accepts 110V or 230V and delivers fully isolated 230V output
Safe in wet environments — galvanic isolation is the standard for electrical safety on boats and in damp workshops
No shared ground — completely eliminates the risk of stray currents and ground faults
Ideal for — marine electronics, service workshops, dental and medical equipment, recording studios
