Intrinsically safe power supply ZIB-2 is a stationary device used to supply intrinsically safe circuits. ZIB-2 is designed in different variations with different input and output parameters and has a built-in battery. Power ZIB-2 is supplied from non-intrinsically safe voltage 42VAC or 230VAC. In the case of a power failure the unit goes into power mode with an external battery.
Each version of the power supply has two communication interfaces: RS-485 and RS-232 interface. To signal the current state of work of the power supply are LEDs on the power supply housing and a set of two-stage inputs.
Intrinsically safe power supply ZIB-2 is a device of M1 category and may thus be used in all underground mines with possible methane or coal dust explosion hazard. It also has 2G category so it can be used by the industry.
Full name is Intrinsically safe power supply ZIB-2/x/x/x/x.
