REDUNDANT FIELD POWER SUPPLY

2/16/2010 9:31 AM	Rate (0)
Behrad Posts: 11 Rating: (0)	I have a question. Is it possible to connect two SITOP power supply outputs directly ( without using of a SITOP redundancy module - 6EP1 961- 3BA20) togetherin order to have a redundant field power supply?

Note that this is connecting two power supplies in parallel, so you must be sure they have exactly the same output voltages, which almost not possible. BR
