A41-25-36L

Power Transformers Overview

The Signal Transformer A41-25-36L is a laminated core power transformer rated at 25 VA, designed for chassis mounting. It features dual primary windings supporting 115 VAC and 230 VAC inputs. The secondary configuration provides parallel 18 VAC at 1.4 A or series 36 VAC at 700 mA. Key electrical specifications include a 4000 Vrms isolation voltage and operation at 50/60 Hz. Physical dimensions are 71.4 mm in length, 54.4 mm in width, and 58.7 mm in height. The unit utilizes quick connect terminals for secure wiring connections.

Power Transformers Feature Summary

• Provides high isolation, creepage, and clearance distances to comply with international safety standards
• Features dual primary and dual secondary winding configurations for versatile voltage input and output options
• Constructed with a laminated core design optimized for industrial control applications

Power Transformers Applications

• Industrial control systems requiring isolated power supplies
• Equipment needing compliance with international safety regulations
• Chassis-mounted electronic assemblies requiring 25 VA power transformation

Power Transformers Procurement Notes

Verify the specific secondary voltage requirement (18V parallel or 36V series) against the application circuit before ordering. Confirm that the chassis mounting style and quick connect terminal type match the existing hardware infrastructure. Ensure the 4000 Vrms isolation rating meets the safety requirements of the target equipment. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Power Transformers Selection Notes

Select this model when a 25 VA laminated transformer with dual primary capability is required for chassis installation. It is suitable for designs needing 115V/230V AC input flexibility. Choose this part over sealed variants if lead wire termination via quick connects is preferred. Consider the physical footprint of 71.4 x 54.4 x 58.7 mm for enclosure space planning. Verify that the 50/60 Hz operating frequency aligns with the system power source.

Power Transformers Part Context

The A41-25-36L belongs to the All-4-One™ International Series by Signal Transformer. This series is engineered to meet diverse global voltage standards using a common form factor. The component serves as a general-purpose power transformer for industrial markets. It replaces older generic transformers where standardized safety isolation and dual-voltage primary support were necessary. The series emphasizes compatibility with international regulatory frameworks.

Power Transformers Replacement Considerations

Direct substitutes may include other models within the A41 series with matching 25 VA ratings and similar secondary configurations. Verify pinout compatibility for quick connect terminals when cross-referencing. Ensure replacement units maintain the 4000 Vrms isolation rating. Generic laminated transformers may lack the specific safety certifications associated with the All-4-One™ line.
