Why Isolation & Ultra-Isolation
Why use an isolation transformer?
A Voltaire isolation transformer creates a dedicated, electrically separated supply for critical loads. It breaks direct electrical continuity with the grid while attenuating noise, spikes, and transients.
Protects against spikes & transients
Buffers voltage spikes, surges, and switching transients coming from the upstream network.
Breaks the direct electrical path
Provides galvanic isolation between input and output, cutting direct conductive paths and improving safety.
Prevents shock hazards
Helps in reducing touch potential and leakage-related risks in specialized installations.
Reduces common-mode noise
Electrostatic shields and optimized winding geometry reduce common-mode and differential-mode noise.
Improves overall power quality
Delivers cleaner, more stable power to precision loads, extending equipment life and reliability.
