A41-130-28

Power Transformers Overview

The A41-130-28 is a single-phase industrial power transformer with a 130 VA rating. It operates at 50/60 Hz and features dual primary windings for 115 VAC or 230 VAC input. The secondary provides 28 VCT at 4.6 A (or 14 V at 9.2 A). It has a 4000 Vrms dielectric strength, chassis mount style, and quick connect/solder lug terminals. Dimensions are approximately 71.4 mm length, 64.3 mm width, and 77.7 mm height.

Power Transformers Feature Summary

• Dual primary and secondary winding configurations for flexible voltage selection
• Chassis mounting design with quick connect and solder lug termination options
• High dielectric strength of 4000 Vrms for enhanced isolation safety

Power Transformers Applications

• Industrial control systems requiring isolated power
• Servo power supply units
• General purpose laminated core transformer applications

Power Transformers Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm terminal type and voltage configuration. Ensure the ordering part number matches the required secondary voltage output (e.g., 28 VCT vs other variants) as suffixes often denote distinct electrical characteristics within the A41 series.

Power Transformers Selection Notes

Select this model when a 130 VA capacity is required for chassis-mounted installations. Confirm that the dual primary winding supports the available line voltage (115 VAC or 230 VAC). Verify that the physical dimensions fit the enclosure and that the quick connect or solder lug terminals are compatible with the PCB or wiring harness design.

Power Transformers Part Context

This component belongs to the A41 international series of laminated core transformers manufactured by Signal Transformer (Bel Fuse). The series offers various power ratings from 80 VA to higher capacities, designed for robust industrial environments. The A41-130-28 specifically addresses mid-range power needs with standardized mounting and connection interfaces.

Power Transformers Replacement Considerations

Direct substitutes include other A41 series models with identical 130 VA ratings but different secondary voltages, such as A41-130-24. Cross-referencing pinouts and physical dimensions is essential when considering alternative manufacturers' equivalents.
