2.Alarm Signal Output
3.Output Voltage TRIM
4.Current Sharing
(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
(3)Table 2.1 explain the alarm function built-in the power supply
(1)Adjustment of output voltage is possible between 70~100%(Typ.) of the rated output which is shown in Fig. 3.1
(2)Connecting a resistor externally between TRIM and-S on CN1 or CN2 that is shown in Fig. 3.2.
(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 4 units is the maximum, please consult the manufacture for other
(5) When remote sensing is used in parallel operation, the sensing wire must be connected only
Function
(+S,-S and LS are connected mutually in parallel):
P OK
is 50V and the maximum sink current is 10mA
(Output current at parallel operation)=(The rated current per unit) x (Number of unit) x 0.9
applications
to the master unit
The signal is "Low" when the power supply is
65% of the rated output voltage-Power OK
The signal turns to be "High" when the power supply
is under 65% of the rated output voltage-Power Fail
