Origin 600 draws 0.625 mA when sleeping, 25 mA when pinging, and 0.146 A when fully active.
The above currents have been calculated using P / V = I, where P = power, V = voltage and I = current.
The Origin 600 ADCP requires 18-48 V external power, so 24 V was taken as a standard voltage. Its power consumption is 15 mW while sleeping, 600 mW while pinging, and 3.5 W when fully active.
