RL-2250-10-24

Power Transformers Overview

The RL-2250-10-24 is a linear power transformer manufactured by Renco Electronics Inc, designed for 50/60 Hz operation. It features a 10VA rating with a dual primary configuration supporting parallel 12V or series 24V inputs. The secondary output provides 24V at 840mA in parallel or 420mA in series via through-hole mounting. Key electrical specifications include an insulation voltage of 4000 VRMS and compliance with UL, CSA, VDE, and IEC safety standards. The unit operates within a temperature range of -40°C to +130°C.

Power Transformers Feature Summary

• Dual primary winding configuration allows flexible input voltage selection between 12V parallel and 24V series connections.
• Shrouded design with low interwinding capacitance eliminates the need for additional electrostatic shielding.
• Includes mounting brackets and quick connector solder terminals for ease of installation.
• Hipot tested at 4000 VRMS to ensure high isolation safety.

Power Transformers Applications

• Industrial control systems requiring isolated power supplies
• Medical equipment needing certified safety isolation
• Test and measurement instrumentation
• General purpose AC-to-DC power conversion circuits

Power Transformers Procurement Notes

Verify that the specific application circuit matches the required primary configuration (parallel 12V or series 24V) and secondary current demands before ordering. Confirm that the chassis mount style fits the mechanical enclosure constraints. Ensure the operating environment stays within the specified -40°C to +130°C range to maintain performance and safety certifications.

Power Transformers Selection Notes

Select this model when a 10VA capacity is sufficient and dual primary flexibility is needed for varying input voltages. The through-hole package and included mounting hardware simplify integration into standard PCB layouts. Consider the physical dimensions and weight if space is limited, as it is not a surface-mount device.

Power Transformers Part Context

This component belongs to the RL-2260 family of All-In-One™ power transformers from Renco Electronics. These units are recognized under UL E132629 and meet international safety specifications. The series is characterized by robust construction, high isolation capabilities, and compliance with RoHS directives for restricted hazardous substances.

Power Transformers Replacement Considerations

Direct substitutes within the same VA rating and form factor should be verified against the datasheet. Check compatibility with existing mounting brackets and terminal configurations. Ensure replacement units maintain the 4000 VRMS insulation rating and identical safety approvals for the target application.
