The failure rate (
) and mean time between failures
(MTBF= 1/
) 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 (
).
Telcordia SR-332 Issue 2 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.

Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2011/65/EU 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.

Isolated DC/DC converters & Power interface modules
© Ericsson AB 2013
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
prior notice.
The product may provide basic or functional insulation
between input and output according to IEC/EN/UL 60950-1
(see Safety Certificate), different conditions shall be met if
the output of a basic or a functional insulated product shall
be considered as safety extra low voltage (SELV).
Safety Specification
General information
Ericsson Power Modules DC/DC converters and DC/DC
regulators are designed in accordance with the safety
standards IEC 60950-1, EN 60950-1 and 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
For basic insulated products (see Safety Certificate) the
output is considered as safety extra low voltage (SELV) if
one of the following conditions is met:
The input source provides supplementary or double or
reinforced insulation from the AC mains according to
IEC/EN/UL 60950-1.
The input source provides functional or basic insulation
from the AC mains and the product’s output is reliably
connected to protective earth according to
IEC/EN/UL 60950-1.
For functional insulated products (see Safety Certificate)
the output is considered as safety extra low voltage (SELV)
if one of the following conditions is met:
The input source provides double or reinforced
insulation from the AC mains according to
IEC/EN/UL 60950-1.
The input source provides basic or supplementary
insulation from the AC mains and the product’s output is
reliably connected to protective earth according to
IEC/EN/UL 60950-1.
The input source is reliably connected to protective
earth and provides basic or supplementary insulation
according to IEC/EN/UL 60950-1 and the maximum
input source voltage is 60 Vdc.
Galvanic isolation between input and output is verified in an
electric strength test and the isolation voltage (V
iso
) meets
the voltage strength requirement for basic insulation
according to IEC/EN/UL 60950-1.
It is recommended to use a slow blow fuse 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
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 and Safety Certificate 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/EN/UL 60950-1
Safety of
Information Technology Equipment.
Product related
standards, e.g. IEEE 802.3af
Power over Ethernet,
and
ETS-300132-2
Power interface at the input to telecom
equipment, operated by direct current (dc)
are based on
IEC/EN/UL 60950-1 with regards to safety.
Ericsson Power Modules DC/DC converters, Power
interface modules 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.
Non - isolated DC/DC regulators
The DC/DC regulator output is SELV if the input source
meets the requirements for SELV circuits according to
IEC/EN/UL 60950-1.

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.
Note 1: Isolation voltage (input/output to base-plate) max 750Vdc.
