3BH45D L

Overview

The Astrodyne TDI 3BH45D L is a high-voltage three-phase power line filter designed for delta configurations. It supports an input voltage of 480V and a current rating of 45A at operating frequencies of 50Hz and 60Hz. The unit utilizes a single-stage filtering architecture with threaded post termination (10-32). Physically, it features a low-profile design with dimensions of 68mm in height, intended for chassis mounting applications requiring efficient electromagnetic interference suppression.

Feature Summary

• High-voltage three-phase power filtering capability
• Low-profile structural design for space-constrained installations
• Single-stage EMC/EMI suppression technology

Applications

• Industrial power supply systems
• Battery charger infrastructure
• Portable electronic device power conditioning

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm terminal type and physical dimensions. Ensure compatibility with 480V delta networks. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated equipment assemblies.

Selection Notes

Select this component for applications requiring robust three-phase noise attenuation in high-voltage environments. Evaluate thermal management requirements based on the 45A continuous current rating. Ensure mechanical clearance accommodates the low-profile form factor and threaded post mounting style.

Part Context

This model belongs to the 3BH series of power line filters from Astrodyne TDI. The series provides modular solutions for electromagnetic interference reduction in industrial and commercial power distribution systems. The 3BH45D L variant specifically addresses high-current delta-connected loads.

Replacement Considerations

Cross-reference with other 3BH series models such as 3BH100D F or 3BH45D F for alternative current ratings or terminal configurations. Verify electrical specifications match before substitution.
