DESCRIPTION
The device also includes a specialized DSP controller that offers best in class immunity to nuisance loads without the need for external analog filters.FEATURES
● 6.0 – 18 Volt Operation (120 − 480 V AC Mains with the Appropriate Series Impedance)● −40 to 85°C
● Very Low Power Consumption: <5 mW @ 5 V
● 16 Pin QFN Package
● Low Cost/Turns Ratio Ferrite Current Transformer (CT) Detection of Differential
● Self Syncing Internal Oscillator Adjusts to AC Mains Frequency to Guarantee Full Resolution on 50 and 60 Hz Distribution Systems
● Optimized Solenoid Deployment (coil is not energized near the AC mains zero crossings)
● Randomized Testing Sequence to Minimize Noise and Potential Interactions on the AC Mains
● >5 mA SCR Driver for Additional Immunity to Supply Noise/Interference
● Superior Immunity to Nuisance Loads/Noise (up to 10 A) without Loss of Detection Capability or CT Saturation
● These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Appl...
