VDC TAKES ON VAC
In the past
Control devices , have required too much power
With
More emphasis on 24 Vdc as the control voltage of choice
those
include programmable logic controllers
Technology advances
appears the power transistors
those
help to reduce
The issues of excessive dc voltage drop over long cable runs
appear a new generation of
Contactors
Starters
Control relays
Sensors
The equipmnet
Is focus on
The importance of personnel protection
using
remote switching and arc-venting switchgear
also
The codes and standards have changed significantly
Focus on
Reduce the potential of exposure to hazardous-touch voltages.
The main objective is prevent the insecurity in the management of the electrical devices
And solve the issues that could happen with the changes
Also
Aspects
