    FAQ

    Q1. What role does the aluminum shield between windings play in this 20 kVA isolation transformer?

    The aluminum shield placed between the primary and secondary windings acts as an electrostatic barrier, reducing capacitive coupling and suppressing high-frequency noise transfer between the input supply and the output circuit. This results in cleaner power delivery to the connected application and provides a higher degree of electrical isolation than non-shielded transformer designs ā€” particularly beneficial in environments with significant electrical noise on the supply line.

    Q2. What voltage configurations are available for this 20 kVA isolation transformer?

    The default configuration converts 240V (primary) to 208V (secondary), with the reverse step-up configuration (208V to 240V) also available. Both primary and secondary voltages are fully customizable across 110V, 120V, 208V, 220V, 230V, and 240V to accommodate project-specific requirements and regional power standards. Please specify your required voltage pairing when placing your order.
