4.Current Sharing
(3)Table 2.1 explains the alarm function built-in the power supply
(1)Alarm signal is sent out through "P OK" & "P OK GND" pins
(2)An external voltage source is required for this function. The maximum applied voltage
Note: Reference voltage terminal, PS and PV are connected when shipping
(1)Parallel operation is available by connecting the units shown as below
(2)The voltage difference among each output should be minimized that less than 2% is required
(3)The total output current must not exceed the value determined by the following equation
(4) In parallel operation 3 units is the maximum, please consult the manufacturer for other
(5) When remote sensing is used in parallel operation, the sensing wire must be connected only
Note : In parallel connection, maybe only one unit (master) operate if the total output load is

The signal is "Low" when the power supply is
15% of the rated output voltage-Power OK
The signal turns to be "High" when the power supply
is under 15% of the rated output voltage-Power Fail
