The remote sense voltage between the supplies must be adjusted to within 2% to ensure the supplies are inside the 3% capture window. If the supplies are not initially adjusted inside the capture window the supplies will not current share. NOTE: “CURRENT SHARING “ facility is inclusive with the unit only with ordering of the “ CURRENT SHARING “ option unit i.e. ABC450-1XXX-I or ABC450-1XXX-I. SET-UP PROCEDURE: 1 Connect load cables to the outputs of each supply. 2 Connect the remote sense lines to the load in twisted style. (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 voltage 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 should 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 not current share.
