panel mount power supply technical information pmc - 24v 3 00w1 b a 14 / 14 rev: 01, 3/21/2011 parallel operation: when 2 power supplies are also connected in the above manner they can share the load provided following steps are taken. step 1: measure the o/p voltages @ nl measured from a1 to gnd i.e. va1 to gnd of psu1 and va2 to gnd of psu2. if the voltages are not same f ollow step 2 , if the o/p voltages are same sk ip step 2 and move to step 3. step 2: adjust the o/p voltages with the help of vr available on the front panel of the psu marked as adjust for both psu1 and psu2 at the same level for e.g. if psu1 o/p is measuring 24.15vdc and psu2 is measuring 24.25vdc adjust the o/p voltage of either psu1 close to 24.25vdc or adjust the o/p voltage of psu2 close to 24.15vdc. step 3: connect the psu to the end system load and measure the o/p voltages from a1 to gnd i.e. va1 to gnd of psu1 and va2 to gnd of psu2. ensu re that o/p voltages are same even after the 2 power supplies are connected to load. if not then adjust them with the vr available on front panel. a tolerance of + 25mv would be acceptable. note: 1 . if the o/p voltage of any 1 power supply i.e. psu1 or ps u2 is higher that power supply will take the initial load and also share the maximum load. 2 . if the o/p voltages adjusted are same then a n equal load current sharing between the 2 power supplies can be achieved. 3 . the oring diode must be of an appropriate rati ng, recommended rating of oring diode is minimum 4 times of the output load current and minimum reverse voltage rating of 45vrr. 4 . a suitable hs is also advised to ensure that oring diode is not over heated and damaged.
