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 TCmax 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 (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 @ 26 V dc.
The case is designed in non-conductive epoxy. Its flammability
rating meets UL 94V-0. The oxygen index is 34%
