RL-2240-4-12

Power Transformers Overview

The RL-2240-4-12 is a 6VA power transformer manufactured by Renco Electronics, Inc. It features a primary voltage of 115V and dual secondary outputs configured for parallel 6.3V or series 12.6V connections. The unit supports a maximum current of 1A in parallel mode and 500mA in series mode. Designed for through-hole mounting, this component operates at 50/60 Hz frequencies. It utilizes a tubular package construction with axial leads, specifically .032-inch tinned copper wire, suitable for general-purpose applications requiring reliable isolation and standard AC-to-AC voltage conversion.

Power Transformers Procurement Notes

Verify the specific secondary configuration requirements against the datasheet before ordering. Confirm that the 6VA rating meets the load demands of the target application. Ensure the physical dimensions and lead spacing are compatible with the intended PCB layout. Check for any updated safety certifications such as UL, CSA, or VDE if required by the final product regulations. Always test sample units in the actual circuit environment to validate performance under real-world conditions.

Power Transformers Selection Notes

Select this model when a compact 6VA transformer with flexible secondary voltage options is needed. Consider the axial lead length and tubular form factor for mechanical clearance constraints. Evaluate the thermal performance relative to the ambient operating temperature range. Compare the DC resistance and leakage inductance specifications against system efficiency requirements. Ensure the primary voltage matches the available line power source frequency and magnitude.

Power Transformers Part Context

This component belongs to the RL-2240 series of power transformers from Renco Electronics. The series is characterized by its dual-transformer design within a single housing, offering space-saving solutions for applications requiring multiple isolated voltages. The RL-2240 series typically provides robust insulation and compliance with international safety standards, making it suitable for commercial and industrial electronic equipment where reliability and regulatory compliance are critical.

Power Transformers Replacement Considerations

Direct substitutes may include other 6VA transformers with identical 115V primary and 6.3V/12.6V secondary ratings. Verify mechanical footprint compatibility, including lead pitch and overall height. Ensure equivalent electrical parameters such as regulation, impedance, and insulation voltage levels. Cross-reference safety approvals to maintain compliance with end-product certification requirements.
