CC Operation
For CC operation, set the output voltages as outlined in CV operation (page 55), or alternatively, program the voltage settings of both outputs to the same voltage limit point. Then program the current of each output so that the sum of both currents equals the total desired operating current. The simplest way to accomplish this is to program each output to one half of the total desired operating current. Both outputs will operate in the CC mode.
Remote Sensing
If it is necessary to remote voltage sense at the load, parallel the sense leads of output 1 with the sense leads of output 2 and connect to the load as shown in Figure

Specifications for Parallel Operation
Specifications for outputs operating in parallel can be obtained from the specifications for single outputs. Most specifications are expressed as a constant or as a percentage (or ppm) plus a constant. For parallel operation, the percentage portion remains unchanged while constant portions or any constants are changed as indicated below. For current readback accuracy and temperature coefficient of current readback, use the minus current specifications:
Current | All parallel specifications referring to current are twice the single output specification except for |
| programming resolution which is the same for both single output and parallel output operation. |
Voltage | All parallel specifications referring to voltage are the same as for a single output except for CV load |
| effect, CV load cross regulation, CV source effect, and CV short term drift. Below 2.5 V, these are |
| all twice the voltage programming accuracy (including the percentage portion). CV load effect |
| above 2.5 V could be twice the load effect specification for a single output. CV output noise for |
| output voltages less than 2.5 V may be slightly higher than the output noise for a single output. |
Load Transient | 350μs maximum to recover within 100 mV of nominal value following a load change within the |
Recovery Time | range of 0 to full load. |
