1.DC_OK Signal
DC_OK is a collector shorted signal. It is used by an optocoupler in the power supply which indicates the output status of the power supply as exhibited below.
2.Redundant function (Current sharing):
LSP-160 has the built-in active current sharing function and can be connected in parallel, up to 2 units, to provide higher output power as exhibited below :
Difference of output voltages among parallel units should be less than 40mV(Can Fine tune by 1).SVR
When in parallel operation the maximum load should not be greater than the rated power of any PSU.
The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
※×When out current<( 30% rate current) (Number of unit),the current shared among units may not be fully balanced.
And the LED indicator maybe flash of one of them,but not effacting normal working.
