Overview
The ECO-105-28 is an industrial power transformer from the ECOtran series by Signal Transformer. It features a 105 VA rating with primary voltage options of 115 V or 230 V. The secondary configuration provides dual outputs: 14 V at 7.4 A and 28 V at 3.7 A (center-tapped). The unit measures 90 mm in length, 106 mm in width, and 106 mm in height. It utilizes screw terminals for connection and is designed for chassis mounting.
Feature Summary
- Provides isolated power conversion for industrial applications
- Supports dual primary voltage inputs for global compatibility
- Offers multiple secondary voltage taps for flexible circuit design
Applications
- Industrial control systems requiring isolated power supplies
- Equipment needing dual voltage rails for logic and power stages
- Chassis-mounted power distribution units
Procurement Notes
Verify the specific terminal configuration and insulation class against the official datasheet before integration. Confirm that the mechanical dimensions align with the designated chassis space. Ensure the primary voltage selection matches the local supply network to prevent operational failure. Cross-reference the secondary current ratings with the actual load requirements to maintain safe operating margins.
Selection Notes
Select this component when a 105 VA isolation barrier is required between primary and secondary circuits. Choose the ECO-105-28 specifically for its dual secondary output capability, which simplifies designs needing both 14 V and 28 V rails. Consider the physical footprint constraints due to its substantial housing size compared to smaller transformers.
Part Context
This model belongs to the ECOtran series, which focuses on industrial-grade power transformers. The series emphasizes robust construction and reliable isolation performance. Signal Transformer manufactures these units to meet stringent industrial standards, ensuring durability in demanding environments where standard commercial components might fail.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model.
