The MX100T from Aim-TTi (Aim Thurlby Thandar) is a 315W precision laboratory power supply’s three outputs can each provide 0 to 35 V at 0 to 3 A. Range switching extends the capabilities so that outputs can be set to 16 V/6 A or 70 V/1.5 A for maximum versatility; where higher power is needed from one output, internal switching circuitry enables up to 210 W arranged as either 35 V/6 A or 70 V/3 A.
All outputs are fully isolated and independent but voltage tracking can be selected to make two or even three outputs track a single voltage control. The isolated tracking capability is useful for creating tracking voltages to different ground points, tracking voltages of opposite polarity, or series and parallel connection of outputs.
