## **Derating Curve** ## **Function Manual** 1. Current sharing - (1) Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel). - (2) Difference of output voltages among parallel units should be less than 0.2V. - (3) The total output current must not exceed the value determined by the following equation (Output current at parallel operation)=(The rated current per unit) x (Number of unit) x 0.9. - (4) In parallel operation 4 units is the maximum, please consult the manufacture for other applications. - (5) The power supplies should be paralleled using short and large diameter wiring and then connected to the load. - (6) When in parallel operation, the minimum output load should be greater than 5% of total output load. - (Min. load >5% rated current per unit x number of unit) - (7) In parallel connection, maybe only one unit (master) operate if the total output load is less than 5% of rated load condition. The other PSUs (slaves) may go into standby mode and their output LEDs & relays will not turn on. - (8) Some minor noise may be heard at light load condition under parallel operation. This is a normal phenomenon and the performance of the PSU will not be influenced. **==> picture [486 x 204] intentionally omitted <==** **----- Start of picture text -----**
