Dear All,

I am looking at creating or buying a DC power supply (100 -240VAC input, 0-70 VDC output (approximately)), that has user adjustable current (0-5amps) and will adjust from the users set current value depending on a 4-20mA input from a flow meter, i.e. if the current is set at 2.8Amps, this would be at a predetermined maximum water flow (20mA), if this flow dropped by half the current would also drop by half, if no flow was present then there would be no current (or very little). the power unit would supply two sets of medical grade silver and copper anodes, immersed in the water flow, so different currents need to be supplied i.e. 40% to one set and 60% to other. any help on this would be very much appreciated

Are you trying to alter dosing pump rates according to measured titration or something similar?
