DATA SHEET
1. Key Features
- -
Precision single-phase, one or two current input energy measurement front-end including SigmaDelta modulators for A/D-conversion and digital signal processor (DSP). Low current consumption of 5mA, depending on MCU activity. Digital phase correction and selectable gain on both current channels for use with two current transformers (CT) or one CT and one shunt. Power-supply monitor (PSM) for power-on reset and reset when the supply voltage falls below a defined threshold....
