5.3.1 CURRENT BALANCING
Current balancing (equalization) conditions required for up to four RKW 300W units in parallel are:
1. Output current of each power supply should be within 20 to 90% of the total output current
rating.
2. The output voltage of any Power Supply individually must be within 2% maximum of the
other power supply output voltage setting.
variation of output voltage in each power supply
3. The expected current sharing is such that the output current variation for each power supply
is less than or equal to 10% of each power supply rated output current.
