Product Code: YR40.242

The N+1 and 1+1 redundant systems are suitable for all DIMENSION power supplies, except the QT20 and QTD20 series. They have a dual input with a single output. At 20 A output current, there is only a 72 mVVoltage drop. The loss at 20 A is only 1.7 W, and at 40 A it is 5.9 W. The system has a peak load capability of 160% (65 A). It also has reverse input polarity protection and can operate at full power between -40°C and +60°C. The width of the system is only 36mm, and it comes in a rugged metal housing. Wiring is made easy with the distribution terminal for the negative pole included.
