Safety
The PKF 4111A I series DC/DC power modules are 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 Canadi-
an 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
temperature to comply with TCmax when in operation. 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 hav-
ing higher rated devices.
When the supply to the DC/DC power module meets all the re-
quirements for SELV (<60 V dc), the output is considered to re-
main 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 (VISO) 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 1A @ 53 V dc. The case is designed in non-
conductive epoxy. Its flammability rating meets UL 94V-0. The
oxygen index is 34%
