RL-2240-3-10

Power Transformers Overview

The RL-2240-3-10 is a linear power transformer manufactured by Renco Electronics, Inc., designed for 50/60 Hz operation. It features a primary voltage rating of 115V and a secondary configuration providing dual outputs: a parallel 5V winding rated at 500mA and a series 10V winding rated at 250mA. The unit has a total power capacity of 2.4VA. It utilizes through-hole mounting technology with axial leads. The transformer is RoHS compliant and meets UL, CSA, VDE, and IEC safety specifications.

Power Transformers Feature Summary

• Dual secondary output capability supporting both parallel low-voltage and series higher-voltage configurations
• Compliance with major international safety standards including UL, CSA, VDE, and IEC
• Through-hole construction with tinned copper wire leads for reliable circuit board integration

Power Transformers Applications

• Low-power AC to DC conversion circuits
• General purpose linear power supplies
• Electronic equipment requiring isolated 5V and 10V rails

Power Transformers Procurement Notes

Verify the specific secondary current ratings against your load requirements before procurement. Confirm that the physical lead spacing matches your PCB footprint design. Ensure the operating frequency aligns with your system's 50Hz or 60Hz input source. Check for any updated safety certifications required by your target market regulations.

Power Transformers Selection Notes

Select this component when a compact linear transformer is needed for low-power applications requiring two distinct secondary voltages. It is suitable for designs where electromagnetic interference from switching regulators is unacceptable. Consider the thermal dissipation characteristics of the 2.4VA rating in enclosed spaces. Verify that the chassis or panel mounting constraints accommodate the physical dimensions of the RL-2240 series.

Power Transformers Part Context

This part belongs to the RL-2240 series of general-purpose power transformers from Renco Electronics. The series typically includes various VA ratings and voltage configurations. These transformers are characterized by their robust construction and compliance with global safety standards, making them suitable for commercial and industrial electronic devices requiring reliable isolation.

Power Transformers Replacement Considerations

Direct replacements must match the 2.4VA rating, 115V primary, and the specific 5V/500mA plus 10V/250mA secondary configuration. Verify that substitute parts maintain the same physical footprint and lead spacing. Ensure equivalent safety approvals (UL, CSA, VDE) are present for regulatory compliance.
