Arc Fault Detector TDAFD7

Talemod TDAFD7 Arc Fault Detector is an independently designed and developed arc fault protection device tailored for both domestic and international electrical environments. The TDAFD7 performs real-time monitoring of electrical circuits for fault arcs. Upon detection of a fault arc, it promptly triggers an alarm and outputs a passive relay trip signal. Additionally, the TDAFD7 supports communication with backend monitoring systems.

Product Overview

The Arc Fault Detection Device (AFDD) is an electrical safety protection equipment based on intelligent arc recognition technology, specifically designed to prevent electrical fires caused by series arcs, parallel arcs, and ground faults. Through high-frequency sampling and arc characteristic analysis algorithms, the device can accurately distinguish hazardous arcs from normal operational arcs, achieving fault interruption within milliseconds. Its core value lies in addressing the technical limitations of traditional circuit breakers and residual current devices, providing a more comprehensive electrical fire protection system for residential, commercial, and industrial premises.

Core Functions

Hazardous Arc Identification: Utilizes multi-frequency characteristic analysis technology to precisely differentiate between normal load operation arcs and dangerous fault arcs.

Millisecond Fast Interruption: Automatically cuts off the circuit within 300ms upon detecting hazardous arc characteristics, preventing arc thermal accumulation from causing ignition.

Self-test and Fault Warning: Features periodic automatic detection function, with indicator blinking to signal device abnormality or circuit aging.

Integrated Multi-protection: Combines overload, short-circuit, and overvoltage protection functions to form a comprehensive electrical fault protection system.
