(a common remote sense point must be used for all the supplies in parallel). 3 connect all the current share pins on the j3 connector between the supplies. 4 adjust remote sense voltage of each supply to within 1% of rated output volt age or readjust to required set point. (adjustment to be done with all other parallel supplies off). 5 current sharing between the supplies can be verified by monitoring the output current of each supply with a hall effect dc current probe. the supplies shou ld share to within 10% of the total load current. 6 the current share circuit has a capture window voltage of +/ - 3% of the rated output voltage. if the output remote sense voltage of one of the supplies is adjusted outside the 3% window the supplies will no t current share. nuclear and medical applications - products are not designed or intended for use as critical components in life support systems, equipment used in hazardous environments, or nuclear control systems. technical revisions - the appearance of products, including safety agency certifications pictured on labels, may change depending on the date manufactured. specifications are subject to change without notice.
