ABB AC800M and S800 IO Power supplies
Power Supplies
The SD83x and SD85x Power Supply Units are designed to meet all the applicable electrical safety
data stated by the EN 50178 harmonized European
Standard Publication and the additional safety and
function data required by EN 61131-2 and UL 508.
The secondary output circuitry is accepted for SELV
or PELV applications.
They are switch-mode Power Supply Units which
convert 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 requirement for the installation of a
mains filter. They provide a soft start feature; power-on of an SD83x will not trip fuses or earth-fault
circuit breakers. The SD822Z is also G3 compliant.
