The AcuDC 300 Series measures DC energy for EV fast-charging systems. The AcuDC-301 configuration combines a 1000 V direct voltage connection and a built-in 650 A shunt with a 24 VDC auxiliary supply. Signed OCMF transaction data, an electronic metrology seal, cable-loss compensation and audit logs support traceable charging measurements.
