RLD-2240-7-24

Power Transformers Overview

The RLD-2240-7-24 is a 36 VA power transformer manufactured by Renco Electronics, Inc. It features a dual primary winding configuration supporting 115V and 230V inputs at 50/60 Hz, selectable via parallel connection. The secondary side provides a center-tapped output with two 12V windings, allowing for 12V parallel operation delivering 3A or 24V series operation delivering 1.5A. This through-hole component is designed for general-purpose AC power conversion applications requiring flexible voltage and current configurations.

Power Transformers Feature Summary

• Dual primary winding design supports both 115V and 230V input voltages
• Center-tapped secondary architecture enables versatile voltage selection
• Through-hole mounting construction for secure board integration

Power Transformers Applications

• General purpose AC power supply units
• Industrial control equipment power stages
• Consumer electronics internal power conversion

Power Transformers Procurement Notes

Verify the specific suffix requirements against the manufacturer's official datasheet to ensure correct pinout and insulation class compatibility. Confirm that the 36 VA rating aligns with the thermal management capabilities of the target enclosure. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the through-hole footprint matches the PCB design specifications before ordering.

Power Transformers Selection Notes

Select this transformer when a single unit must support multiple input voltage standards without rewiring changes. The dual secondary configuration allows designers to choose between higher current at lower voltage or higher voltage at reduced current based on load requirements. Consider the physical size constraints associated with 36 VA through-hole transformers compared to smaller surface-mount alternatives.

Power Transformers Part Context

This component belongs to the RLD-2240 series of power transformers from Renco Electronics. The series typically offers various VA ratings and secondary configurations. The RLD-2240-7-24 specifically denotes the 36 VA variant with the defined 115/230V primary and split-secondary secondary options. It is part of a broader family of industrial-grade transformers designed for reliability in standard frequency operations.

Power Transformers Replacement Considerations

Direct substitutes include other Renco models within the RLD-2240 series that match the 36 VA rating and identical winding ratios. Verify that any replacement maintains the same through-hole package dimensions and terminal spacing. Cross-reference electrical parameters such as isolation voltage and temperature rise limits to ensure equivalent performance in the existing circuit design.
