The PeakTech 6215 is a laboratory power supply which has 4 separate voltage outputs. All voltage outputs can be continuously adjusted using the rotary controls, which are attached to the sides of the front. The rotary controls make it possible to freely set the voltage and current for CH1 and CH2. With channels 3 and 4, only the voltages can be set because they have fixed current values. It is also possible to use the two push-buttons for switching to normal, serial and parallel, to set the type of interconnection of the independently controllable outputs.
