Jun 10, 2009 Based on Hall Effect technology, TD and 9001 Current Detectors protect power semiconductors in power electronic circuits by signaling when current in circuit has exceeded nominal trip point. Digital output is factory programmed to go low when trip point is exceeded. Operating over temperature range of -40 to +125°C, units mount directly to PCB and provide isolation between sensed current and output. Both have negligible levels of power dissipation.
