The PKH 2000 I series is a range of DC/DC power
modules for 24 V DC systems. The PKH is based on
the highly reliable and proven Macro Dens™ PKF
series and adopted to the industry standard central
pin-out. The PKH power modules have high
efficiency and very low idling input current, which
makes them ideal as distributed power sources in
decentralized power systems with battery back-up.
They are optimized for free convection cooling and are
designed for an operational ambient temperature
range of –40 to +75°C in compliance with present
and future application needs. In addition to the
industry standard functionality turn-on and turn-off
can be realized by using the optional RC pin. They
can also operate in parallel for redundancy and power
upgrading.
These products are manufactured using highly
automated manufacturing lines with a world-class
quality commitment and a five-year warranty.
Ericsson Microelectronics AB has been an ISO 9001
certified supplier since 1991.

Stress in excess of Absolute Maximum Rat-
ings 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 Charac-
teristics. If exposed to stress above these lim-
its, function and performance may degrade
in an unspecified manner.

Safety
The PKH Series DC/DC power modules are designed in accordance
with EN 60 950,
Safety of information technology equipment including
electrical business equipment.
Semko certification no. 9819405.
The PKH power modules are recognized by UL and meet the appli-
cable requirements in UL 1950
Safety of information technology equip-
ment,
the applicable Canadian safety requirements and UL 1012
Standard for power supplies.
The DC/DC power module shall be installed in an end-use equip-
ment and considerations should be given to measuring the case tem-
perature to comply with T
C max
when in operation. Abnormal compo-
nent tests are conducted with the input protected by an external 3 A
fuse. The need for repeating these tests in the end-use appliance shall
be considered if installed in a circuit having higher rated devices.
The isolation is an operational insulation in accordance 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
requirements of the ultimate application. 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 con-
nectors 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 Tele-
phone Equipment, second edition).
The galvanic isolation is verified in an electric strength test. Test
voltage (V
ISO
) between input and output is 1,500 V dc 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 1µA @ 26 V dc.
The case is designed in non-conductive epoxy. Its flammability
rating meets UL 94V-0. The oxygen index is 34%
.
