Safety
The PKF 4110B I DC/DC power module meets the isolation
requirements of UL/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
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

production the test duration may be decreased to 1 s.
The capacitor between input and output has a value of 1nF 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%.
