RLD-2240-2-10

Power Transformers Overview

The RLD-2240-2-10 is a 1.1VA power transformer manufactured by Renco Electronics, Inc., designed for through-hole mounting. It operates at 50/60 Hz with a dual primary configuration supporting 115V and 230V inputs in parallel. The secondary side offers versatile output options: a parallel connection provides 5V at 220mA, while a series connection yields 10V at 110mA. This component facilitates efficient voltage conversion for low-power electronic applications requiring flexible secondary voltage configurations.

Power Transformers Feature Summary

• Dual primary winding configuration supports both 115V and 230V input voltages via parallel connection.
• Versatile secondary output allows selection between 5V parallel or 10V series configurations.
• Through-hole mounting design ensures secure integration into printed circuit boards.

Power Transformers Applications

• Low-power electronic equipment requiring isolated AC-to-DC power supply stages
• Industrial control systems utilizing 5V or 10V secondary logic circuits
• Consumer electronics adapters needing compact 1.1VA power transformation

Power Transformers Procurement Notes

Verify the specific secondary configuration required (parallel 5V or series 10V) against the application schematic before ordering. Confirm that the through-hole footprint matches the PCB layout constraints. Ensure the operating frequency aligns with the 50/60 Hz specification. Cross-reference the manufacturer's datasheet to validate insulation ratings and thermal performance for the intended enclosure environment.

Power Transformers Selection Notes

Select this transformer when a small form factor and low power consumption are critical. It is suitable for designs needing either 5V or 10V secondary outputs without additional complex wiring. Consider the thermal dissipation capabilities of the 1.1VA rating within the final assembly. Evaluate if the through-hole mounting style meets the mechanical stability requirements of the product.
