Absolute Maximum Ratings

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 Output data or Electrical Characteristics.

If exposed to stress above these limits, function and performance may degrade in an

unspecified manner.

Safety

The PKV 3000 I and PKV 5000 I series

DC/DC converters are designed in

accordance with safety standards

UL 60 950-1, SafetyofInformation

TechnologyEquipment. The PKV

3000 I and PKV 5000 I series DC/

DC converters are UL 60 950-1

recognized. The DC/DC converter

should be installed in the end-use

equipment, in accordance with

the requirements of the ultimate

application. The input source must be

isolated by minimum Basic insulation

from the primary circuit in accordance

with UL 60 950-1. If the input voltage

to the DC/DC converter is 72 V dc or

less, then the output remains SELV

(Safety Extra Low Voltage) under

normal and abnormal operating

conditions.

It is recommended that a slow blow

at the input of each DC/DC converter.

If a fault occurs in the converter that

imposes a short circuit on the input

source, this fuse will provide the

following functions:

• Isolate the faulty DC/DC converter

from the input power source not to

affect the operation of other parts of

the system.

• Protect the distribution wiring from

excessive current and power loss

thus preventing hazardous overhea-

ting.

The galvanic isolation is verified in an

electric strength test. The test voltage

Vdc for 60 seconds. Leakage current is

less than 1µA at nominal input voltage.

The flammability rating for all

construction parts of the DC/DC

converter meets UL 94V-0.
