Overview
The Signal Transformer 14A-2.5R-10 is a laminated power transformer designed for industrial applications. It operates at 50 Hz or 60 Hz with a power rating of 2.5 VA. The unit features a single primary winding rated at 115 VAC and a secondary configuration providing 10 VCT at 0.25 A. Constructed for through-hole mounting, it measures 41.3 mm in length, 28.6 mm in height, and weighs 113 g.
Feature Summary
- Laminated core construction for standard power transformation
- Through-hole pin terminal interface for board integration
- Single primary winding with dual secondary voltage output
Applications
- Industrial control circuit power supply
- Servo system auxiliary power
- General purpose low-power AC to AC conversion
Procurement Notes
Verify the specific datasheet version (1 or 2) as referenced by distributors to ensure dimensional and electrical compliance. Confirm that the 115 VAC primary input matches your system voltage. Check RoHS status details on the manufacturer's official documentation before finalizing procurement orders.
Selection Notes
Select this component when a compact, low-power transformer is required for chassis or PCB mounting. Ensure the 0.25 A secondary current capacity meets the load requirements. Consider the physical dimensions of 41.3 mm x 28.6 mm for enclosure space planning. Verify compatibility with 50/60 Hz line frequencies.
Part Context
This model belongs to the International Series of power transformers from Bel Signal Transformer. It is categorized under board-mount power transformers suitable for general industrial use. The series provides standardized solutions for converting mains voltage to lower control voltages in compact form factors.
Replacement Considerations
Cross-reference with other 2.5 VA laminated transformers from Signal Transformer's 14A series. Verify identical pinout configurations and voltage ratings before substitution. Consult official distributor databases for confirmed substitute part numbers.
