Overview
The Vigortronix VTX-146-1000-145 is a toroidal power transformer with a 1000VA rating and chassis mount configuration. It features a single 230V primary winding. The secondary output provides parallel 45V or series 90V options at full load, supporting a maximum current of 11.11A. The unit measures 71mm in diameter and 167mm in length, designed for robust industrial power conversion applications requiring high capacity and stable voltage delivery.
Feature Summary
- Toroidal core construction for efficient magnetic flux linkage
- Chassis mounting design for secure installation
- Dual secondary voltage configuration options
Applications
- Industrial power supply units
- High-capacity audio amplification systems
- Medical equipment power stages
Procurement Notes
Verify the specific secondary voltage requirement (parallel 45V vs. series 90V) against the target circuit design before ordering. Confirm that the chassis mounting dimensions and terminal types match the enclosure specifications. Ensure the primary voltage matches the local mains supply standard to prevent operational failure.
Selection Notes
Select this model when a high-power toroidal transformer is required for chassis-mounted installations. The 1000VA rating suits heavy-duty loads. Consider the physical dimensions of 71mm x 167mm for space constraints. Verify thermal management needs given the high power density of the toroidal design.
Part Context
This component belongs to the Vigortronix VTX-146 series of toroidal transformers. The series is characterized by high efficiency and low electromagnetic interference. The VTX-146-1000-145 represents the 1000VA capacity variant within this lineup, offering versatile secondary voltage configurations for diverse power distribution needs.
Replacement Considerations
Cross-reference part numbers such as VTX-146-1000-140 for similar 1kVA ratings but different secondary voltages. Ensure any substitute maintains the same chassis mounting footprint and toroidal form factor to fit existing enclosures without modification.
