    Overview

    The single-phase 1 kVA isolation transformer offers reliable, cost-effective voltage conversion between 240V and 120V AC,  in both step-down and step-up configurations. The sealed IP20 enclosure provides effective protection against dust, moisture, and mechanical shock, while the cold-rolled oriented silicon steel core delivers low core loss and stable magnetization characteristics.  A multi-hole enclosure design with rear-mounted cooling fan maintains optimal operating temperatures, and an LCD digital display with two-color indicator lights offers clear, at-a-glance voltage monitoring. Four 360Ā° universal casters complete the package for flexible on-site positioning.

    FAQ

    Q1. Can the input and output voltages of this 1 kVA isolation transformer be customized?

    Yes. While the default configuration converts 240V (primary) to 120V (secondary), both input and output voltages are fully customizable. Supported options include 110V, 120V, 208V, 220V, 230V, and 240V on both sides. Step-up configurations (e.g., 120V to 240V) are equally available. Please specify your required voltage pairing at the time of order.

    Q2. What is the advantage of choosing copper wire winding over aluminum wire?

    Copper enameled wire offers higher electrical conductivity and greater resistance to thermal fatigue compared to aluminum wire, making it the preferred choice for applications with higher continuous load demands or longer operating cycles. Aluminum wire winding provides a cost-effective alternative where budget is the primary consideration, with no compromise to the transformer's rated efficiency or insulation class.
