Detailed signal description

Power fail detect H

Open-collector signal reference to SEC Ground. A current limited 10K - 1.4W

resistor is connected to the collector of the output transistor for this signal.

The PFD H signal will be asserted, i.e. the transistor will open, when the input

voltage goes below 170VAC.

Power good L

Open-collector signal reference to SEC Ground. A current limiting 10K -

1.4W resistor is connected to the collector of the output transistor for this

signal.

The power good signal goes high, i.e. the transistor will open, when the

output voltage is out of specification or if the input power factor correction

stage is not functioning.

Inhibit H +, -

This is a differential signal that is connected to an internal opto-coupler.

When the differential voltage applied between these two signals exceeds

3.5V, the output voltage is disabled. When the signals are less than 0.9V, the

output shall be enabled. The current drain is less than 6mA with the

differential voltage less than 3.5V.

Unit present L

This pin is tied to SEC GND and can be used to detect the presence of the

unit in a system.

Current monitor

This is an analog output proportional to the output current and is referenced

to output -. The signal consists of a voltage source connected through a 10K

- 1.4W - 1% resistor to this pin and delivers a signal whose value is 0.1 x

Iout. The signal is within the specified accuracy of

current is greater than 6.0A.
