11. Protection Features

Output over-current protection not included

Reverse input polarity

protection

included Unit does not start when input voltage is reversed.

Degree of protection IP 20 EN/IEC 60529

Penetration protection > 3.6mm e.g. screws, small parts

Over-temperature protection not included

Input transient protection not included

Output transient protection included See EMC section.

Internal input fuse not included

12. Safety Features

Input / output separation no galvanic separation Mosfet between input and output

Class of protection III PE (Protective Earth) or chassis connection not required

PE resistance < 0.1Ohm between housing and chassis-ground terminal

13. Dielectric Strength

The input and output voltages have the same reference, are oating and have no ohmic connection to the ground.

Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the eld using the

appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect input/output

terminals together before conducting the test.

When testing, set the cut-off current settings to the value in the table below.
