RLD-2240-2-24

Power Transformers Overview

The RLD-2240-2-24 is a 1.1VA power transformer manufactured by Renco Electronics, Inc., designed for through-hole mounting. It features a dual primary winding configuration supporting 115V and 230V inputs at 50/60 Hz, selectable via parallel connection. The secondary output provides two configurations: a parallel arrangement delivering 12V at 90mA, or a series arrangement providing 24V at 45mA. This component serves as a linear isolation transformer suitable for low-power electronic applications requiring specific voltage step-down capabilities.

Power Transformers Feature Summary

• Dual primary winding design allows flexible input voltage selection between 115V and 230V systems
• Configurable secondary outputs enable either 12V parallel or 24V series operation modes
• Through-hole construction facilitates standard printed circuit board integration

Power Transformers Applications

• Low-power AC to DC power supply stages
• Industrial control equipment isolation
• Consumer electronics internal power distribution

Power Transformers Procurement Notes

Verify the specific secondary configuration required for your application before procurement. The part supports both 12V parallel and 24V series secondary connections; ensure wiring matches the intended output voltage and current rating. Confirm that the 1.1VA power rating meets the load requirements of the target circuit to prevent overheating or performance degradation during continuous operation.

Power Transformers Selection Notes

Select this model when a compact, low-power transformer is needed for universal input compatibility. The choice between 12V and 24V output depends on downstream circuit requirements. Ensure the PCB layout accommodates through-hole pins and that the thermal environment supports the 1.1VA dissipation. Verify that the 90mA or 45mA current limits align with the maximum load demand of the connected components.

Power Transformers Part Context

This component belongs to the RLD-2240 series from Renco Electronics, which specializes in general-purpose power transformers. The series typically offers various VA ratings and voltage combinations. The RLD-2240-2-24 specifically addresses niche requirements for small form-factor devices needing isolated low-voltage DC generation from standard mains frequencies.

Power Transformers Replacement Considerations

Direct replacements must match the 1.1VA rating, dual primary 115/230V capability, and through-hole package. Secondary voltages (12V/24V) and currents (90mA/45mA) must be compatible. Check pinout compatibility and physical dimensions to ensure fit within existing enclosures without modifying the PCB footprint.
