Note:
1) The input voltage range 36...75 V meets
the requirements in the European Telecom
Standard prETS 300 132-2 for Normal input
voltage range in 48 V and 60 V DC power
systems, –40.5...–57.0 V and –50.0...–72.0 V
respectively.
Safety
The PKD 4000 SI Series DC/DC power
modules are designed in accordance with
EN 60 950 Safety of information technology
equipment including electrical business
equipment, and certied by UL.
The isolation is an operational insulation in
accordance with EN 60 950.
The PKD DC/DC power modules are re-
cognized by UL and meet the applicable re-
quirements in UL 1950 Safety of information
technology equipment, the applicable Cana-
dian safety requirements and UL 1012 Stan-
dard for power supplies. The DC/DC power
module shall be installed in an end-use
equipment and is intended to be supplied by
isolated secondary circuitry and shall be in-
stalled in compliance with the requirements
of the ultimate application. When the supply
to the DC/DC power module meets all the
requirements for SELV (<60Vdc), the output
is considered to remain within SELV limits
(level 3). If connected to a 60 V DC power
system reinforced insulation must be pro-
vided in the power supply that isolates the
input from the ac mains. Single fault testing
in the power supply must be performed in
combination with the DC/DC power module
to demonstrate that the output meets the
requirement for SELV. One pole of the input
and one pole of the output is to be grounded
or both are to be kept oating. The terminal
pins are only intended for connection to
mating connectors of internal wiring inside
the end-use equipment.
These DC/DC power modules may be used
in telephone equipment in accordance with
paragraph 34 A.1 of UL 1459 (Standard for
Telephone Equipment, second edition).
The isolation voltage is a galvanic isolation
and is veried in an electric strength test.
Test voltage between input and output is
1500 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 2.2 nF and the leakage current is
less than 1A @ 50 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
unspecied manner.
