Note:
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 unspecied manner.

Environmental Characteristics
Safety
The PKB 4000 series DC/DC converters
are designed in accordance with safety
standards IEC/EN/UL 60 950, Safety of
Information Technology Equipment. The
PKB 4000 series DC/DC converters are
UL 60 950 recognized and certied in
accordance with EN 60 950.
The DC/DC converter should be installed
in the end-use equipment, in accordance
with the requirements of the ultimate
application. The input source must be
isolated by minimum Basic insulation
from the primary circuit in accordance
with IEC/EN/UL 60 950. If the input
voltage to the DC/DC converter is 75 V
dc 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 V dc. If the input power
source circuit is a DC power system,
the source may be treated as a TNV2
circuit and testing has demonstrated
compliance with SELV limits and
isolation requirements equivalent to Basic
insulation in accordance with
IEC/EN/UL 60 950.
It is recommended that a fast blow fuse
with a rating of 5A be used at the input
of each DC/DC converter. The PKB se-
ries DC/DC converters are approved for
a maximum fuse rating of 15A. If a fault
occurs in the converter that imposes a
short circuit on the input source, this fuse
will provide the following functions:
Isolate the faulty DC/DC converter
from the input power source 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.
The galvanic isolation is veried in an
electric strength test.
The test voltage
(VISO) between input and output is 2250
Vdc for 60 seconds. Leakage current is less
than 1A at nominal input voltage.
The ammability rating for all
construction parts of the DC/DC
converter meets UL 94V-0.
