cliq ii redundancy module 20a 40a www.deltapsu .com 5 parallel operation when 2 power supplies are connected in parallel, they can share the load if the following steps are taken. step1. measure th e output voltages at no load from anode1 to ground i.e. voltage anode1 to ground of psu1 and voltage anode2 to ground of psu2. if the voltages are not the same, follow step 2. if they are the same, skip to step 3. step2. . adjust the output voltages, with the help of vr on the po wer supply front panel market as adjust, to the same level. for e.g. if psu1 is measuring 24.15vdc and psu2 is measuring 24.25vdc, adjust the output voltage of one to be the same as the other step3. connect the power supply to the end system load and meas ure the output voltages from a1 to ground i.e. voltage anode 1 to ground of psu1 and voltage anode 2 to ground of psu2. ensure that the output voltages are the same even after the 2 power supplies are connected to load. if not, adjust them with the vr avai lable on the front panel. a tolerance of +/ - 25mv would be acceptable. note 1 ) if the output voltage of any power supply is higher, it will take the initial load and share the maximum load. 2 ) if the output voltages are the same, then an equal load current sharing between the 2 power supplies can be achieved. 3 ) the oring diode must be of an appropriate rating. the rating must be at least 4 times of the output load current and at least reverse voltage rating of 20vrr. 4 ) the use of a heat sink is advised to ensure the oring diode does not overheat. 5 ) recommended redundancy module: drr - 20a redundancy operation with drp 20a - (40a)
