Typical inrush current waveforms of CM, CMZ, EM, LM
and LMZ DC-DC converter with option E
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 CM, EM, LM and CMZ, LMZ mod-
ules with a nominal output power of 51 W maximum.

E Electronic Inrush Current Limitation
Available for CM, EM, LM and CMZ, LMZ types.
The standard version of the modules CM, DM, EM, LM as
well as CMZ, DMZ, LMZ include a passive inrush current
limitation in the form of a NTC resistor.
For applications which require an improved inrush current
limitation, an active electronic circuit as shown in fig.
Option
E block diagram has been developed. Typical inrush cur-
rent 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 ETS 300132-2 if fitted with
option E combined with option D6 (input voltage monitor-
ing). Option D6, externally adjustable via potentiometer, is
necessary to disable the converter at input voltages below
the actual service ranges, avoiding an excessive input cur-
rent when the input voltage is raised slowly according to
ETS 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 appli-
cations where potentiometers are not allowed refer to op-
tion D9.

F Fuse Not Accessible
The standard M units have a fuseholder containing a 5
× 20
mm fuse which is externally accessible and to be found in
the back plate near the connector. Some applications re-
quire an inaccessible fuse. Option F provides a fuse moun-
ted directly onto the main PCB inside the case.
The full self-protecting functions of the module do normally
not lead to broken fuses, except as a result of inverse polar-
ity at the input of an AM, BM, CM, FM or CMZ type or if a
power component inside fails (switching transistor, free-
wheeling diode, etc). In such cases the defective unit has to
be returned to Power-One for repair.
H Enhanced Electric Strenght Test
Electric strength test voltage output to case 2800 V DC
(2000 V AC) instead of 1400 V DC (1000 V AC).
