FAQ
Q1: What load can a 500 VA toroidal transformer support?
A1: A 500 VA toroidal transformer comfortably powers devices up to 450 W continuous load (e.g., laptop chargers, LED TVs). Always leave a 20% safety margin for startup currents.
Q2: How do I choose between the 1000 VA and 2000 VA models?
A2: Sum the wattage of all devices you plan to run simultaneously. For example, if your appliance total is 1.2 kW, select the 2000 VA model to allow headroom and prevent overheating.
Q3: Where can I find the best toroidal transformer price?
A3: Contact our sales team for volume discounts and customized quotations. We offer competitive pricing across all capacities—guaranteeing the best toroidal transformer price without sacrificing performance.
