RLD-2240-4-12

Power Transformers Overview

The RLD-2240-4-12 is a power transformer manufactured by Renco Electronics, Inc., designed for general-purpose applications operating at 50/60 Hz. It features a primary winding configuration supporting parallel connections for 115V and 230V input voltages. The secondary side offers dual output options: a parallel connection providing 6.3V at 1A, or a series connection delivering 12.6V at 500mA. With a total power rating of 6VA, this component utilizes through-hole mounting technology for integration into printed circuit boards.

Power Transformers Feature Summary

• Supports dual primary voltage inputs via parallel wiring for 115V and 230V operation
• Provides flexible secondary output configurations with parallel 6.3V or series 12.6V capabilities
• Utilizes through-hole mounting for secure PCB integration

Power Transformers Applications

• General purpose power supply circuits
• Electronic equipment requiring isolated AC power conversion
• Industrial control systems utilizing standard line frequencies

Power Transformers Procurement Notes

Verify the specific pinout and physical dimensions against the official datasheet before integration, as mechanical tolerances are critical for through-hole assembly. Confirm that the required current ratings (1A parallel or 500mA series) align with the load requirements of the target application to ensure safe thermal operation within the 6VA limit.

Power Transformers Selection Notes

Select this model when a compact 6VA transformer is needed for standard 50/60Hz mains frequencies. Ensure the design accommodates the specific secondary current limits; the device cannot sustain 1A at the higher series voltage simultaneously. Consider the through-hole footprint constraints during PCB layout planning.

Power Transformers Part Context

This component belongs to the RLD-2240 series from Renco Electronics, which specializes in dual/transformer designs for various industrial and commercial needs. The series typically includes variants with different voltage and VA ratings, allowing engineers to select appropriate isolation transformers based on specific power and voltage conversion requirements.

Power Transformers Replacement Considerations

Direct substitutes must match the 6VA rating, 115/230V primary, and 6.3V/12.6V secondary outputs. Verify mechanical compatibility and pin alignment. Cross-reference part numbers like RLD-2240-3-48 only if electrical parameters differ significantly.
