04DKPS4E(D)

Overview

The Delta Electronics 04DKPS4E(D) is a single-phase, two-stage EMI line filter designed for noise-sensitive applications. It features a plastic case and supports both DIN rail and threaded mounting configurations. The component operates at a maximum continuous voltage of 250 V AC with a rated current of 4 A at 50/60 Hz. It includes a protective hinged cover and offers low leakage performance. The unit is certified by UL, CSA, ENEC, CE, and UKCA, and complies with RoHS standards.

Feature Summary

• Two-stage filtering architecture within a compact plastic enclosure
• Flexible installation options including DIN rail and threaded mounting
• Protective hinged cover design for terminal safety
• Low leakage current characteristics suitable for sensitive equipment

Applications

• Medical devices requiring strict electromagnetic compatibility
• Automation systems and industrial control panels
• Servo motor drives and robotic arm controllers
• General purpose industrial machinery

Procurement Notes

Verify the specific suffix (D) against official datasheets to confirm mounting configuration details. Check manufacturer discontinuation notices as this series may be subject to end-of-life status. Ensure compliance with local certification requirements such as UL or CE before integration. Confirm availability through authorized distributors due to potential supply constraints on legacy components.

Selection Notes

Select this model for applications requiring two-stage attenuation in space-constrained environments. The plastic housing reduces weight compared to metal alternatives while maintaining necessary insulation properties. Verify that the 4 A rating meets the load requirements. Consider the (D) suffix if DIN rail mounting is preferred over chassis mounting for easier system integration.

Part Context

This component belongs to the DKP series of single-stage and two-stage EMI filters manufactured by Delta Electronics. The series is engineered for industrial automation and medical equipment. The 04DKPS4E(D) variant specifically denotes the 4 A rating with enhanced filtering stages and specific mounting options, distinguishing it from standard single-stage models in the same family.

Replacement Considerations

Consult official substitution lists for direct replacements. Generic equivalents may not match the two-stage performance or specific mounting dimensions. Verify that any substitute maintains the required 250 V AC rating and 4 A current capacity.
