Example: Product number BMR 461 3001/001C equals a 12A, LGA, PMBus
and analog pin strap, standard configuration variant.
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
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).

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.
Mean steady-state failure rate,
λ
40 nFailures/h
Std. deviation,
σ
8.2 nFailures/h
MTBF (mean value) for the BMR 461 series = 24.98 Mh.
MTBF at 90% confidence level = 19.77 Mh
The information and specifications in this technical
specification is believed to be correct at the time of
publication. However, no liability is accepted for
inaccuracies, printing errors or for any consequences
thereof. Ericsson AB reserves the right to change the
contents of this technical specification at any time without

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.
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.
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.
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.
If the input power source circuit is a DC power system, the
source may be treated as a TNV-2 circuit and testing has
demonstrated compliance with SELV limits in accordance
with IEC/EN/UL60950-1.
Non-isolated DC/DC regulators
The input voltage to the DC/DC regulator is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.

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 in the Electrical Specification. If exposed to stress above these limits, function and performance
may degrade in an unspecified manner.
Configuration File
This product is designed with a digital control circuit. The control circuit uses a configuration file which determines the functionality and performance of the product.
The Electrical Specification table shows parameter values of functionality and performance with the default configuration file, unless otherwise specified. The default
configuration file is designed to fit most application needs with focus on high efficiency. If different characteristics are required it is possible to change the
configuration file to optimize certain performance characteristics.
In this Technical specification examples are included to show the possibilities with digital control. See Operating Information section for information about trade offs
when optimizing certain key performance characteristics.
