【英文介绍】

The SD83x Power Supply Units are designed to meet allthe applicable

electrical safety data stated bythe EN 50178 harmonized European

Standard Publication and the additional safety and function data

required by EN 61131-2 and UL 508.

The secondary outputcircuitryis accepted for SELV or PELV

applications.   They are switch-mode Power Supply Units thatconvert

the mains voltage to 24 volts d.c. These power supplies can be

utilized for non-redundant and redundant applications.

Redundant applications require diode voting units SS823 or SS832.

With the type SD83x series Power Supply Units,there is no

requirementfor the installation of a mains filter.   They provide a soft

startfeature;   power-on of an SD83x will nottrip fuses or earth-fault

circuit breakers

Features and benefits

Simple DIN-rail mounting

Class I Equipment, (when connected to Protective Earth, (PE))

Over-voltage CategoryIII forconnection to primary main

TN network

Protective separation of secondarycircuitfromprimarycircuit

Accepted for SELV and PELV applications

The output of the units is protected against overcurrent

(currentlimit) and over-voltage (OVP)

Both a.c. and d.c. input at SD831 and SD834
