RL-2240-3-12

Power Transformers Overview

The RL-2240-3-12 is a linear power transformer manufactured by Renco Electronics, Inc., designed for 50/60 Hz operation. It features a primary voltage of 115V configured in parallel and dual secondary outputs. The secondary windings provide 6.3V at 400mA in parallel configuration and 12.6V at 200mA in series configuration. This component utilizes a through-hole mounting style and is RoHS compliant.

Power Transformers Feature Summary

• Dual secondary winding design supporting parallel and series output configurations
• Low interwinding capacitance with shrouded construction to eliminate electrostatic shielding requirements
• Hipot tested at 4000 VRMS for enhanced safety isolation
• Includes mounting brackets and quick connector solder terminals for ease of installation

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Industrial control systems requiring isolated power
• Consumer electronics utilizing linear power regulation

Power Transformers Procurement Notes

Verify the specific part number suffix against the manufacturer's current datasheet to ensure correct secondary voltage and current ratings. Confirm that the required mounting style matches the chassis or PCB layout constraints. Check for updated compliance certifications such as UL, CSA, VDE, and IEC standards before finalizing procurement orders.

Power Transformers Selection Notes

Select this model when a dual-output transformer is needed for separate parallel and series secondary connections. Ensure the primary voltage matches the available line voltage of 115V. Consider the physical dimensions and through-hole lead spacing to verify compatibility with the target assembly board or chassis mounting points.

Power Transformers Part Context

This component belongs to the RL-2260 and RL-2240 series of All-In-One™ power transformers from Renco Electronics. These units are characterized by their compact size, high insulation capabilities, and integrated mounting hardware. The series is widely used in applications requiring reliable, isolated power conversion with minimal external component requirements.

Power Transformers Replacement Considerations

Direct substitutes within the same family include models like RL-2240-3-10 and RL-2240-3-24, which share similar form factors but differ in secondary voltage ratings. Verify electrical parameters match exactly before substitution.
