Safety
The PKF 5713 I DC/DC power module is designed in accordance
with EN 60 950, Safety of information technology equipment including
electrical business equipment. The PKF power modules are recognized by
UL and meet the applicable 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
equipment and considerations should be given to measuring the
case temperature to comply with T
Abnormal component tests are conducted with the input protected
by an external 15 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
requirements 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 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 galvanic isolation is verified in an electric strength test. Test
voltage (V
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%.
