FIT AC Mains and Zero Crossing Precision Detector - FlameIT - Immersion Cooling

Features

• very accurate mains zero crossing detection
• fully isolated (5kV optoisolation)
• low voltage, safe output (low side can be supplied with voltages from 1V up to 16V)
• ultra-low power consumption; worst case power dissipation < 120mW
• produces symmetrical pulses around the zero crossing
• works over all mains voltage ranges (100VAC…240VAC), without any modification
• both 50Hz (1,2ms ZC pulse) and 60Hz (1ms ZC pulse) mains frequency compatible
• highly stable with varying temperature
• ROHS compliant (Pb-free)
• extra AC input protection (fuse and varistor)
• 4 independent AC inputs on one module
• 2 low side outputs for each AC input
• ZCD - Zero Crossing Detection pulse (HIGH level pulled to GND)
• MDL - Mains Detection Logic (HIGH when mains is detected)
• spring clamp system terminal blocks on input and output
• extra goldpin outputs on low side

Use cases

• Mains detection (logical output HIGH when phase is available)
• ZCD - Zero Crossing Detection
• Mains frequency monitoring
• Checking of connection order of three phase systems
• Checking shift between phases
• Detection of power failures
• AC motor monitoring
• other…
