説明
- TIDA-00498, Signal Processing Subsystem and Current Input Based Self Power for Breaker Applications (ACB/MCCB). The reference design features signal processing front-end and self-power block for electronic trip unit (ETU) used in circuit breakers. A FRAM based micro-controller is used for processing current inputs from signal conditioning amplifiers for 3-phase, neutral and ground current. Two gains are used to extend the range for phase current measurement. This reference design can also self-power using rectified current input. TIDA-00498 is designed for fast and repeatable tripping (within 30mS) for wide current and temperature range
