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.
