1.7 SUPERVISORY SIGNALS (Typical Connection)

The following supervisory signals are accessible:

•

DC OK

•

AC FAIL

•

PS EXIST

•

TEMP ALARM

Fig-1.7

SIGNAL RETURN and mentioned signals are isolated from the output terminals and -SENSE.

These signals are Open Collector type (max 15V, max 10mA) shunted by internal 24V zener,

isolated from Output and referenced to “SIGNAL RETURN”.

Open collector signals are shunted by internal 24V zener

1.6. OUTPUT VOLTAGE PROGRAMMING by External Voltage.

Output Voltage of HFE1600 Series can be programmed by external voltage source between approximately 80%-120% for

24V, 32V, 48V and 80%-110% for 12V of nominal output voltage (For Output voltage limits see Graph enclosed).
