The 3020-01097-0 is a Base-mounted DC Shunt is designed for measuring DC currents from 5 to 1200A. These precision shunts (+/-0.25% accuracy) connect directly to MPS's DCA5-20PC Series of DC ammeters. Installation is straightforward: simply connect the load circuit to the shunt's threaded studs and the shunt's mV Kelvin outputs to the digital ammeter's input terminals.
