SE15C

Overview

The Astrodyne TDI SE15C is a single-output, AC-DC switching power supply designed for industrial and commercial applications. It delivers a nominal output voltage of 15V DC with a maximum current capacity of 1.0A, resulting in a total power rating of 15W. The unit features universal input voltage acceptance ranging from 85 to 264V AC at 47-63Hz, ensuring compatibility with global power standards. Key electrical specifications include a line regulation of +/-1% and load regulation of +/-2%. The device incorporates comprehensive protection mechanisms including short-circuit, overload, and over-temperature protection, operating within a temperature range of -25°C to +70°C.

Feature Summary

• Universal AC input capability supporting worldwide voltage standards
• Integrated multi-protection circuitry for short-circuit and thermal safety
• Compact metal housing designed for efficient heat dissipation

Applications

• Industrial control systems requiring stable low-voltage DC power
• Telecommunications equipment powering remote terminal units
• Medical diagnostic devices needing isolated power supplies

Procurement Notes

Verify the specific part number suffix against the manufacturer's latest datasheet to confirm pinout configuration and connector type. Ensure that the required input voltage range matches your local grid specifications. Confirm compliance certifications such as UL or CE are present on the documentation for your target market. Check for any recent design changes that may affect mounting dimensions or terminal assignments before finalizing procurement orders.

Selection Notes

Select this model when a compact, reliable 15W DC source is needed for sensitive electronics. Consider the thermal environment; while it operates up to 70°C, derating may be necessary in enclosed spaces. Verify that the load does not exceed the 1.0A continuous current limit. Evaluate if the fixed output voltage meets the system requirements without need for external adjustment. Compare physical dimensions against available panel space or chassis mounting options.

Part Context

This component belongs to the SE series of AC-DC converters from Astrodyne TDI, known for robust construction in harsh environments. The series typically offers various wattage ratings and output voltages to suit diverse industrial needs. Units in this family generally share similar form factors and protection profiles, facilitating standardized design integration across multiple product lines within automation and instrumentation sectors.

Replacement Considerations

Direct replacements must match the 15V/1.0A output specification and physical footprint. Verify pin compatibility for existing wiring harnesses. Cross-reference with other manufacturers' 15W DIN-rail or panel-mount supplies only if mechanical and electrical interfaces are identical. Ensure replacement units maintain equivalent isolation voltage and protection levels.
