[sense(+) ? sense(?)] = 0.5 v the voltage between the v o (+) and v o (?) terminals must not exceed 53 v. this limit includes any increase in voltage due to remote-sense compensation and out- put voltage set-point adjustment (trim). see figure 12. if not using the remote-sense feature to regulate the output at the point of load, then connect sense(+) to v o (+) and sense(?) to v o (?) at the module. although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. the maximum increase is the larger of either the remote sense or the trim. consult the factory if you need to increase the output voltage more than the above limitation. the amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. when using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power. sense(+) v o (+) sense(?) v o (?) v i (?) + ? i on/off on/off v i (+) load v on/off
