RLD-2240-2-12

Power Transformers Overview

The RLD-2240-2-12 is a 1.1VA power transformer manufactured by Renco Electronics, Inc., designed for through-hole mounting. It features a primary winding rated for 115V and 230V operation at 50/60 Hz, configured in parallel. The secondary output provides dual configurations: a parallel connection yielding 6.3V at 180mA, or a series connection providing 12.6V at 90mA. This component serves as a standard electrical isolation device for low-power applications requiring specific voltage step-down capabilities.

Power Transformers Feature Summary

• Provides isolated power conversion with configurable secondary voltage outputs via series or parallel wiring.
• Supports dual primary input voltages of 115V and 230V for global compatibility.
• Utilizes through-hole technology for secure PCB integration.

Power Transformers Applications

• Low-power electronic equipment requiring 6.3V or 12.6V secondary rails
• Control circuits operating on 50Hz or 60Hz mains frequencies
• Industrial instrumentation needing galvanic isolation

Power Transformers Procurement Notes

Verify the specific pinout configuration required for your circuit design, particularly regarding the primary parallel connection and secondary series/parallel options. Confirm that the 1.1VA rating meets the thermal and load requirements of the target application. Ensure the through-hole footprint matches the PCB layout specifications before finalizing procurement orders to avoid assembly issues.

Power Transformers Selection Notes

Select this transformer when a compact, low-voltage solution is needed for 115V/230V inputs. It is suitable for designs where either 6.3V at higher current or 12.6V at lower current is preferred. Consider the physical size constraints and the need for through-hole mounting when evaluating alternatives within the Renco RL series.

Power Transformers Part Context

This part belongs to the RLD series of power transformers from Renco Electronics, Inc., which are characterized by their robust construction and suitability for general-purpose power supply applications. The series typically offers various VA ratings and voltage combinations to accommodate diverse electronic design requirements.

Power Transformers Replacement Considerations

Direct substitutes must match the 1.1VA rating, 115/230V primary, and 6.3V/12.6V secondary specifications. Check mechanical dimensions and pin assignments for compatibility. Other Renco models with identical electrical parameters may serve as functional replacements if availability differs.
