TRICON EPI3382 | Enhanced Power Interface Module

Technical Specifications

Key Features and Advantages

The EPI3382 delivers fault-tolerant power distribution with triple modular redundancy (TMR) architecture, ensuring uninterrupted operation in critical safety systems. Its active current sharing technology maintains voltage regulation within ±0.5% across parallel modules.

Advanced diagnostics: Features real-time load monitoring with predictive failure alerts through integrated voltage/current sensors. The module’s arc-resistant design prevents energy discharge during hot swapping, complying with NFPA 70E arc flash safety requirements.

Energy efficient operation: Achieves 94% efficiency through zero-voltage switching (ZVS) technology. The conformal coated PCB withstands 98% humidity in harsh environments while maintaining galvanic isolation between input and output circuits.
