Overview
The NBH-30-471-D is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It features a two-stage filtering architecture designed for high-performance noise suppression in sensitive electronic systems. The unit supports AC voltages up to 250 VAC and DC voltages up to 250 VDC, with a continuous current rating of 30 A. It utilizes push-down terminal connections for secure wiring and is intended for DIN rail mounting applications.
Feature Summary
- Two-stage EMI/EMC filtering architecture for enhanced noise attenuation
- Low leakage current design suitable for medical and sensitive equipment
- Push-down terminal connection system for rapid installation
- DIN rail mounting style for compact panel integration
Applications
- Medical device power supplies requiring low leakage current
- Industrial control panels needing robust EMI suppression
- Telecommunications equipment power input stages
- Precision measurement instruments sensitive to line noise
Procurement Notes
Verify the specific suffix '-D' indicates DIN rail mounting configuration distinct from chassis mount variants like NBM. Confirm voltage ratings match the application's AC or DC requirements. Ensure the 30 A current capacity aligns with peak load demands. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this model when DIN rail mounting is preferred over chassis mounting. Compare against NBM series if chassis mounting is necessary instead. Verify that the 250 VAC/VDC rating meets the system voltage. Consider the two-stage design benefits for strict EMI environments compared to single-stage alternatives.
Part Context
This component belongs to the NBH series of power line filters from Cosel. It shares the core filtering technology with the NBM series but differs in mounting style and terminal type. The series is part of Cosel's broader portfolio of EMI filters designed for various industrial and commercial power conditioning needs.
Replacement Considerations
NBM-30-471 is a chassis-mount equivalent within the same family. Verify mounting compatibility before substitution. Other NBH variants may offer different capacitance values or current ratings.
