For bench and panel-based commissioning where AC mains is always available, battery management adds nothing but complexity. The CRA160LSi-A is AC-powered (100–240V input) and delivers 6 voltage channels at 130V each, with current output configurable as 6×20A or 3×40A depending on whether you're testing two independent 3-phase circuits or one circuit at higher current. Amplitude accuracy holds to ±0.1% guaranteed, with phase accuracy at 0.05° typical — tight enough for differential and distance relay commissioning where angle precision matters as much as magnitude. If you're comparing AC-mains test sets in this class, check whether the competing unit's current output is fixed or switchable — that flexibility changes which test scenarios a single unit can actually cover.
