3. cuit The 6V output current limit depends on the output termi nal voltage and varies linearly between 2 75 amps at 6 volts and 1 amp at zero volts All controls digital meter and output terminals are located on the front panel One voltage control sets the 0 to 6V and another sets the voltages of the O to 20V and 0 to 20V outputs simul taneously These dual tracking outputs are made more versatile by providing a tracking ratio control in addition to the usual volt age control With the tracking ratio control turned fully clockwise to its fixed position the dual outputs have a fixed 1 1 tracking ratio As the 20V voltage control is adjusted the voltage of the negative supply tracks the positive output within 1 Turning the tracking ratio control away from its fully clockwise position switches the dual tracking outputs into a variable tracking ratio mode In this mode the voltage of the negative output can be set lower than that of the positive output The tracking ratio control allows the negative supply s output to be set to any value between a maximum that is within 5 of the positive supply s output and a minimum that is less than 0 5 volts Once a ratio is established by the tracking ratio control the ratio of the positive output voltage to the negative output voltage remains constant as the 20V voltage control varies the O to 20V output over its range The front panel also contains a line switch three overload indicators
4. factory regulation at the load Each pair of connecting wires should be as short as possible and twisted or shielded to reduce noise pick up If a shield is used connect one end to the supply ground terminal and leave the other end unconnected If load considerations require locating output power distribu tion terminals at a distance from the power supply then the power supply output terminals should be connected to the remote distribution terminals by a pair of twisted or shielded wires and each load should be connected to the remote distri bution terminals separately Parallel Operation Two or more supplies can be connected in parallel to obtain a total output current greater than that available from one sup ply The total output current is the sum of the output currents of the individual supplies The output voltage controls of one power supply should be set to the desired output voltage and the other supply set for a slightly larger output voltage The supply set to the lower output voltage will act as a constant voltage source while the supply set to the higher output will act as a current limited source dropping its output voltage until it equals that of the other supply The constant voltage source will deliver only that fraction of its rated output current 1 8 necessary to fulfill the total current demand Series Operation Series operation of two or more power supplies can be accomplished up to the output isolation r
