General Information
Reliability
The failure rate (
λ
) and mean time between failures
(MTBF= 1/
λ
) is calculated at max output power and an
operating ambient temperature (T
A
) of +40°C. Ericsson
Power Modules uses Telcordia SR-332 Issue 2 Method 1 to
calculate the mean steady-state failure rate and standard
deviation (
σ
).
Telcordia SR-332 Issue 2 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.

MTBF (mean value) for the BMR453 series = 3 Mh.
MTBF at 90% confidence level = 2.1 Mh
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Ericsson
Power Modules products are found in the Statement of
Compliance document.
Ericsson Power Modules fulfills and will continuously fulfill
all its obligations under regulation (EC) No 1907/2006
concerning the registration, evaluation, authorization and
restriction of chemicals (REACH) as they enter into force
and is through product materials declarations preparing for
the obligations to communicate information on substances
in the products.
Quality Statement
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, Six Sigma, and SPC are intensively in use to
boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
work force, contribute to the high quality of the products.

Warranty period and conditions are defined in Ericsson
Power Modules General Terms and Conditions of Sale.
Limitation of Liability
Ericsson Power Modules does not make any other
warranties, expressed or implied including any warranty of
merchantability or fitness for a particular purpose (including,
but not limited to, use in life support applications, where
malfunctions of product can cause injury to a person’s
health or life).

The information and specifications in this technical
specification is believed to be correct at the time of

thereof. Ericsson AB reserves the right to change the

prior notice.
IEEE 802.3
CSMA/CD (Ethernet) Access Method,
and
ETS-300132-2
Power supply interface at the input to
telecommunications equipment, operated by direct current
(dc),
but all of these standards are based on
IEC/EN/UL 60950-1 with regards to safety.
Ericsson Power Modules DC/DC converters and DC/DC
regulators are UL 60950-1 recognized and certified in
accordance with EN 60950-1.
The flammability rating for all construction parts of the
products meet requirements for V-0 class material
according to IEC 60695-11-10,
Fire hazard testing, test
flames
– 50 W horizontal and vertical flame test methods.
The products should be installed in the end-use equipment,
in accordance with the requirements of the ultimate
application. Normally the output of the DC/DC converter is
considered as SELV (Safety Extra Low Voltage) and the
input source must be isolated by minimum Double or
Reinforced Insulation from the primary circuit (AC mains) in
accordance with IEC/EN/UL 60950-1.
Isolated DC/DC converters
It is recommended that a slow blow fuse is to be used at
the input of each DC/DC converter. If an input filter is used
in the circuit the fuse should be placed in front of the input
filter.
In the rare event of a component problem that imposes a
short circuit on the input source, this fuse will provide the
following functions:
•
•
Isolate the fault from the input power source so as
not to affect the operation of other parts of the
system.
Protect the distribution wiring from excessive
current and power loss thus preventing hazardous
overheating.
Safety Specification
General information
Ericsson Power Modules DC/DC converters and DC/DC
regulators are designed in accordance with safety
standards IEC/EN/UL 60950-1
Safety of Information
Technology Equipment.
IEC/EN/UL 60950-1 contains requirements to prevent
injury or damage due to the following hazards:
•
•
•
•
•
•
Electrical shock
Energy hazards
Fire
Mechanical and heat hazards
Radiation hazards
Chemical hazards
On-board DC/DC converters and DC/DC regulators are
defined as component power supplies. As components
they cannot fully comply with the provisions of any safety
requirements without “Conditions of Acceptability”.
Clearance between conductors and between conductive
parts of the component power supply and conductors on
the board in the final product must meet the applicable
safety requirements. Certain conditions of acceptability
apply for component power supplies with limited stand-off
(see Mechanical Information for further information). It is
the responsibility of the installer to ensure that the final
product housing these components complies with the
requirements of all applicable safety standards and
regulations for the final product.
Component power supplies for general use should comply
with the requirements in IEC 60950-1, EN 60950-1 and
UL 60950-1
Safety of Information Technology Equipment.
There are other more product related standards, e.g.
The galvanic isolation is verified in an electric strength test.
The test voltage (V
iso
) between input and output is
1500 Vdc or 2250 Vdc (refer to product specification).
24 V DC systems
The input voltage to the DC/DC converter is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.
48 and 60 V DC systems
If the input voltage to the DC/DC converter is 75 Vdc or
less, then the output remains SELV (Safety Extra Low
Voltage) under normal and abnormal operating conditions.
Single fault testing in the input power supply circuit should
be performed with the DC/DC converter connected to
demonstrate that the input voltage does not exceed
75 Vdc.

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are
normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and
performance may degrade in an unspecified manner.
Note 1: Isolation voltage (input/output to base-plate) max 750Vdc.
