RL-2250-56-20

Power Transformers Overview

The RL-2250-56-20 is a 56VA power transformer from the Renco Electronics RL-2250 series. It features dual 115V primary windings configurable for parallel (10V) or series (20V) operation at 50/60 Hz. The secondary provides a 20V center-tapped output, delivering 2.8A in series configuration or 5.6A in parallel. Designed for through-hole mounting, it includes UL, CSA, VDE, and IEC safety certifications.

Power Transformers Feature Summary

• Dual primary winding design allows flexible voltage input configurations
• Center-tapped secondary output supports multiple current ratings
• Complies with international safety standards including UL and VDE
• Shrouded construction minimizes electrostatic shielding requirements

Power Transformers Applications

• Industrial control systems requiring isolated power
• Medical equipment power supplies
• Commercial appliance transformers
• General purpose AC to DC conversion stages

Power Transformers Procurement Notes

Verify that the specific order matches the required primary voltage configuration (parallel vs. series) and secondary current rating. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors prior to procurement. Ensure mounting hardware compatibility with the through-hole PCB layout.

Power Transformers Selection Notes

Select this component when a 56VA isolation transformer is needed with flexible primary voltage options. The dual 115V primary allows adaptation to different regional line voltages. Choose the series or parallel secondary connection based on the required output current and voltage levels for the specific circuit design.

Power Transformers Part Context

This part belongs to the RL-2250 International Series of laminated power transformers. The series is characterized by compact physical dimensions and broad global regulatory approvals. It serves as a standard solution for applications requiring reliable isolation between primary mains and secondary loads.

Power Transformers Replacement Considerations

Direct substitutes within the same VA rating and pinout are limited. Verify mechanical dimensions and electrical parameters against alternatives such as other models in the RL-2250 family or competing brands like Hammond or Triad before substitution.
