DP-241-7-56L

Overview

The Signal Transformer DP-241-7-56L is a laminated core power transformer designed for chassis mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The secondary winding provides a 56 VAC center-tapped output with a maximum current rating of 1 A, delivering a total power capacity of 56 VA. Key electrical specifications include an isolation voltage of 2500 Vrms and an operating temperature range from -40°C to +105°C. The unit utilizes screw termination style and adheres to RoHS compliance standards.

Feature Summary

• Dual primary winding configuration supports flexible input voltage selection between 115V and 230V AC systems.
• Center-tapped secondary design enables versatile rectification circuits for critical power applications.
• Chassis mount construction ensures secure installation in industrial enclosures.
• High isolation voltage rating provides enhanced safety protection between primary and secondary circuits.

Applications

• Industrial control panel power supplies
• Equipment requiring isolated DC power rails
• Low power critical height applications
• General purpose AC to DC conversion stages

Procurement Notes

Verify the specific suffix 'L' against official manufacturer documentation to confirm exact physical dimensions or terminal variations compared to standard models. Ensure compatibility with existing chassis cutouts and mounting hardware before procurement. Cross-reference the datasheet for precise weight and thermal dissipation requirements to validate system integration constraints.

Selection Notes

Select this component when a 56 VA capacity with a 56V CT secondary is required for chassis-mounted installations. The dual primary winding allows direct connection to either 115V or 230V mains without rewiring. Consider the -40°C to +105°C operating range for environments with significant thermal fluctuations. Verify that the screw termination style matches the available PCB or wire harness interface.

Part Context

This model belongs to the Two-4-One series of single-phase transformers manufactured by Signal Transformer. The series is characterized by standardized footprints and high efficiency designs suitable for various industrial and commercial power supply architectures. It serves as a fundamental building block for converting standard line voltages to lower, regulated levels required by electronic circuitry.

Replacement Considerations

Direct substitutes may include models from Triad Magnetics within similar power and voltage classes. Verify pinout compatibility and mechanical footprint dimensions before substitution. Ensure the replacement part meets or exceeds the 2500 Vrms isolation requirement and maintains the same thermal performance characteristics.
