ESM-03-471-D

Power Line Filter Modules Overview

The Cosel ESM-03-471-D is a single-phase power line filter module designed for AC and DC applications. It supports a voltage rating of 250 VAC and 250 VDC with a current capacity of 3 A. The unit features a low leakage current of 50 uA and utilizes a 470 pF capacitance value. It employs screwless terminal block connections and is intended for DIN rail mounting. The component weighs approximately 170 grams and is packaged in bulk quantities.

Power Line Filter Modules Feature Summary

• Provides common mode noise filtering for power lines
• Ensures low leakage current operation for safety compliance
• Utilizes screwless terminal blocks for simplified wiring

Power Line Filter Modules Applications

• Industrial control panels requiring DIN rail integration
• Medical equipment power supplies
• Electronic instrumentation systems

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and terminal compatibility before integration. Ensure the application environment does not exceed the rated voltage or current limits. Confirm RoHS compliance status if required by project specifications. Check for any specific mounting hardware requirements associated with the DIN rail style.

Power Line Filter Modules Selection Notes

Select this model when a compact, single-stage filter is needed for low-current circuits. The screwless connection method offers faster installation compared to traditional screw terminals. Consider the 50 uA leakage current specification for sensitive applications where ground fault protection is critical. Verify that the DIN rail profile matches standard industrial mounting rails.

Power Line Filter Modules Part Context

This component belongs to the ESM series of power line filters manufactured by Cosel USA, Inc. The series focuses on providing EMC/EMI suppression for single-phase power inputs. The ESM-03-471-D variant specifically addresses the 3 A current requirement within this product family.

Power Line Filter Modules Replacement Considerations

The ESM-03-471 is the non-DIN rail chassis mount equivalent. The EAM-03-471-D is a similar DIN rail mounted alternative from the same manufacturer.
