The PKS Series DC/DC power modules are
designed in accordance with EN 60 950,
Safety of information technology equipment
including electrical business equipment.
The PKS power modules are recognized by
UL and meet the applicable requirements in
UL 1950 Safety of information technology equip-
ment and the applicable Canadian safety re-
quirements.
The DC/DC power module shall be installed
in an end-use equipment and considerations
should be given to measuring the case tem-
perature to comply with TCmax when in op-
eration. Abnormal component tests are con-
ducted with the input protected by an exter-
nal 3 A fuse. The need for repeating these
tests in the end-use appliance shall be con-
sidered if installed in a circuit having higher
rated devices.
When the supply to the DC/DC power mod-
ule is isolated and meets all the requirements
for SELV (<60Vdc), the output is considered
to remain within SELV limits (level 3). The
isolation is an operational insulation in ac-
cordance with EN 60 950.
The DC/DC power module is intended to be
supplied by isolated secondary circuitry and
shall be installed in compliance with the re-
quirements of the ultimate application.The
power module is evaluated with the second-
ary output referenced to earth.
The terminal pins are only intended for
connection to mating connectors of internal
wiring inside the end-use equipment.
The galvanic isolation is verified in an
electric strength test. Test voltage (VISO)
between input and output is 1,500 Vdc for
60 s. In production the test duration may be
decreased to 1 s.
The capacitor between input and output has
a value of 1 nF and the leakage current is less
than 5 A @ 50 Vdc.
Safety
Stress in excess of Absolute Maximum
Ratings may cause permanent damage. Ab-
solute Maximum Ratings, sometimes re-
ferred to as no destruction limits, are nor-
mally tested with one parameter at a time
exceeding the limits of Output data or Elec-
trical Characteristics. If exposed to stress
above these limits, function and performance
may degrade in an unspecified manner.
1)
Corresponding ambient temperature range
(TA) at full output power is – 40 to +85 °C
mounted on a printed circuit board in free
convection. See also Thermal Data.
