General
Safety
The PKG 2000 I Series DC/DC power mod-
ules are designed in accordance with EN 60
950, Safety of information technology equipment
including electrical business equipment and certi-
fied by SEMKO.
The PKG 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 TCmax 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 connect-
ed 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
connection 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 (VISO) between input and output
and between case and output is
1,500 Vdc (duals = 1,000 V dc) for 60 s.
In production the test duration may be de-
creased to 1 s.
The capacitor between input and output has a
value of 4.7 nF (duals = 22 nF) and the leak-
age current is less than 1mA @ 26 Vdc.
Flammability ratings of the terminal support
and internal plastic construction details
meets UL 94V-0.
Absolute Maximum Ratings
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.

Note:
1) The input voltage range 19...36 V meets
the requirements for Normal input voltage
range in 24 V DC power systems, 20…30 V.
At input voltages exceeding 36 V (abnormal
voltage) the power loss will be higher than at
normal input voltage and TC must be limited
to max +90 °C. Absolute max continuous
input voltage is 40 V dc. Output characteris-
tics will be marginally affected at 18 V (see
also Turn-off Input Voltage).
