The PKF Series DC/DC power modules are designed in accordance
with EN 60 950,
Safety of information technology equipment including
electrical business equipment
.
SEMKO certificate no. 9709166.
The PKF power modules are recognized by UL and meet the applica-
ble requirements in UL 1950
Safety of information technology equipment
,
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 pin tem-
perature to comply with T
Pmax
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.
When the supply to the DC/DC power module meets all the require-
ments for SELV (<60Vdc), the output is considered to remain within
SELV limits (level 3). 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. If they are connected to a
60 V DC system reinforced insulation must be provided in the power
supply that isolates the input from the 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 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 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 1 nF and the
leakage current is less than 1μA @ 53 Vdc.
The case is designed in non-conductive epoxy. Its flammability
rating meets UL 94V-0. The oxygen index is 34%
.
