Precautions:
In order to avoid overload of the series resistor RI the on/off
switching cycle should be limited to 12 s if switched on/off
continuously. There should not be more than 10 start-up
cycles within 20 s at a case temperature of 25
°C.
If CM and CMZ types are driven by input voltages below
35 V DC or LM and LMZ types below 100 V AC, the maxi-
mum case temperature should be derated by 10 K or the to-
tal output power should be derated by 20%. EM, LM and
LMZ units driven by DC input voltages do not need to be
derated within the full specified input voltage range.
Availability:
Option E is available for C/E/LM and CMZ/LMZ modules
with a nominal output power of 51 W maximum.

Option E Extended inrush current limitation
Available for C/E/LM and C/LMZ types.
The standard version of the modules C/D/E/LM as well as
C/D/LMZ include a passive inrush current limitation in the
form of a NTC resistor.
For applications which require an extended inrush current
limitation, an active electronic circuit as shown in "Option E
block diagram" has been developed. Typical inrush current
waveforms of units equipped with this option are shown
below.
CM and CMZ units meet the CEPT/ETSI standards for
48 V DC supply voltage according to prETS 300132-2 if fit-
ted with option E combined with option D6 (input voltage
monitoring). Option D6, externally adjustable via poten-
tiometer, is necessary to disable the converter at input volt-
ages below the actual service ranges, avoiding an exces-
sive input current when the input voltage is raised slowly
according to prETS 300132-2. Option D6 threshold level
Uti
+
Uhi (refer to description of option D) should be adjusted
to 36.0...40.5 V for 48 V DC nominal supply voltage (for 60
V DC systems, threshold should be set to 44.0...50.0 V
DC). The D output (pin 5) should be connected to the inhibit
(pin 2). For applications where potentiometers are not al-
lowed refer to option D9.
