A41-43-515

Power Transformers Overview

The A41-43-515 is a laminated power transformer from the International Series, rated at 43 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz. The secondary configuration provides 5 VDC at 2 A and ±15 VDC at 250 mA. Designed for chassis mounting, it measures 79.4 mm in length, 54.4 mm in width, and 68.2 mm in height. The unit utilizes quick connect terminals for electrical interfacing and offers a dielectric strength of 4000 Vrms.

Power Transformers Feature Summary

• Dual primary winding capability for flexible input voltage selection between 115 VAC and 230 VAC.
• Integrated multi-output secondary design providing both low voltage DC and isolated bipolar rails.
• Robust chassis mount construction with quick connect termination style for secure installation.

Power Transformers Applications

• Industrial control systems requiring multiple isolated voltage rails
• Chassis-mounted equipment needing 5V logic and ±15V analog supply
• General purpose industrial power distribution units

Power Transformers Procurement Notes

Verify that the specific order matches the A41-43-515 designation to ensure correct 43 VA rating and output configuration. Confirm chassis mounting compatibility with the target enclosure dimensions. Ensure input voltage requirements align with the dual primary winding specifications before integration.

Power Transformers Selection Notes

Select this component when a single transformer must provide 5V, +15V, and -15V outputs simultaneously. The 43 VA rating supports loads up to 2A on the 5V rail and 250mA on the auxiliary rails. Consider the physical footprint of 79.4 x 54.4 x 68.2 mm for mechanical clearance.

Power Transformers Part Context

This model belongs to the International Series of laminated transformers manufactured by Signal Transformer. It is part of the All-for-One Micropro line, designed to consolidate multiple power functions into a single compact unit. The series emphasizes reliability for industrial environments with standard chassis mounting capabilities.

Power Transformers Replacement Considerations

The A41-25-515 is a related model within the same series but offers a lower 25 VA rating. It provides identical secondary voltages but with reduced current capacity (130 mA/1.25 A). Verify if the load requirements exceed the 25 VA limit before considering this alternative.
