Stress in excess of Absolute Maximum
Ratings may cause permanent damage.
Absolute MaximumRatings, 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.

Safety
The PKA 2000 I Series DC/DC power
modules are designed in accordance with
EN 60 950,
Safety of information technology
equipment including electrical business equipment
and certified by
SEMKO.
The PKA power modules are recognized by
UL and meet the applicable requirements in
UL 1950
Safety of information technology equip-
ment
, the applicable Canadian safety require-
ments and UL 1012
Standard for power sup-
plies
.
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 T
Cmax
when in
operation. They are intended to be supplied
by isolated secondary circuitry and shall be
installed in compliance with the require-
ments of the ultimate application. If con-
nected to a 24 V DC power system reinforced
insulation must be provided in the power
supply that isolates the input from the ac
mains. The isolation in the DC/DC power
module is an operational insulation in accord-
ance with EN 60 950. One pole of the input
and one pole of the output is to be grounded
or both are to be kept floating.
The terminal pins are only intended for con-
nection to mating connectors of internal
wiring inside the end-use equipment.
The isolation voltage is a galvanic isolation
and is verified in an electric strength test.
Test voltage (V
ISO
) between input and output
is 500 Vdc.
The capacitor between input and output has a
value of 10 nF and the leakage current is less
than 1 A @ 26Vdc.
Flammability ratings of the terminal support
and internal plastic construction details
meets UL 94V-0.
