Dividers of a power supply and overvoltage protection

Power supply dividers

A power supply and outcome at application in the zones Ex

Operation principle

Dividing devices separate intrinsically safe current contours from not intrinsically safe contours. Such devices differ in parameters of a power supply and technical datas of intrinsic safety.

Application

These devices are used in need of execution of requirements of intrinsic safety.

Devices of overvoltage protection

Protection against the increased tension

Operation principle

These devices limit possible an overstrain to noncritical values, thereby preventing failures and malfunctions in operation of the connected devices. The choice of the device is defined by opportunities of mounting and parameters of necessary protection of a power supply or a current contour.

Application

These devices have common industrial application.
