General
Safety
The PKB 4000 PI Series DC/DC converters
are designed in accordance with North
American and International Safety Regulatory
Agency Requirements per IEC/EN 60 950,
Standards for Safety of Information Technology
Equipment.
The PKB 4000 Series DC/DC converters are
Recognized by UL and CSA in accordance
with ULC 1950 and ULC 60 950 and are
TUV Type Certified as per EN 60 950.
The DC/DC converters should be in-stalled in
end-use equipment, in compliance with the
requirements of the ultimate application. If
the input is 75Vdc or less, then all the
outputs remain SELV under normal and
abnormal operating conditions. However,
when the supply voltage exceeds 60Vdc,
minimum Basic Insulation must be provided
in accordance with IEC 60 950, isolating the
input power supply from the AC mains.
Single fault testing in the input power supply
circuit should be performed with the DC/DC
converter connected to demonstrate that the
input voltage does not exceed 75Vdc. If the
input power supply circuit is a DC power
system, the source maybe treated as a TNV2
circuit and testing has demonstrated
compliance with SELV limits and isolation
requirements equivalent to Basic Insulation in
accordance with IEC/EN/UL 60 950.
It is recommended that a fast blow fuse with a
rating of 5A be used at the input of each
PKB converter. However, the converters are
approved for a maximum fuse rating of 15A.
If a fault occurs in the converter that imposes
a short on the input source, this fuse will
provide the following two functions:
Isolate the failed converter from the input
source so that the remainder of the system
may continue operation.
Protect the distribution wiring from
overheating.
The galvanic isolation is verified in an electric
strength test. The test voltage (VISO) between
input and output is 2250 Vdc for 60 seconds.
Leakage current is less than 1uA.
Note:
Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings,
sometimes referred to as "no destruction limits", are normally tested with one parameter at a time
exceeding the limits of the Output data or Electrical Characteristics.
