Features
Integrated e-metering function with 0.5% accuracy
<10% iTHD at 0–10% load, <5% iTHD at 10%–20% load, <3% iTHD at 20%–50% load, <2% iTHD at 50%–100% load
Peak efficiency of 98.93% at 230Vac
Smart re-rush current control when AC comes back from dropout, meet M-CRPS re-rush current specification
Include baby boost converter to extend holdup time and allow only 720µF bulk cap
Two current sense options: Isolated Delta-Sigma Modulator (default) or Hall Sensor
GaN optimized with driver integration
3.6kW rated power targeting 73.5mm M-CRPS PSU
