Over Current Programming by External Voltage
Over Current Protection (OCP) can be programmed by external voltage source 0~5V. By changing the Current
Programming Voltage OCP level could be decreased down to ~40% of Nominal Output Current.

SUPERVISORY Signals (Typical Connection)
The following supervisory signals are accessible:
DC OK
AC FAIL
PS EXIST
TEMP ALARM
Figure 3–13:
Signals
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”.
