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).

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.
Note: As an example a negative logic with non-threaded stand off product
would be PKY 2616 PINM.
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 PKY series = 2.6 Mh.
MTBF at 90% confidence level = 2.3 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.

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.
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

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

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.
