The intrinsically safe iBA12-14 battery power supply ensures a mains independent power supply of electrical equipment in intrinsically safe systems for use in hazardous, firedamp areas. It provides protection acc. to type EEx ib I

The power supply unit NG3-16ib-0.3 enables the power supply of electrical equipment items operated in intrinsi-cally safe systems within hazardous locations which are susceptible to firedamp. The power supply unit NG3-16ib-0.3 provides protection as per I M 2 EEx m [ib] I. Based on a non-intrinsically safe AC input voltage, a regulated, current-limited and intrinsically safe of 16 VDC / 0.2 A is generated in the output cir-cuit. The device is preferably used for the remote powering of the line ampli-fier of the Mobil Radio System MR90.

The power supply unit NG3-12ib enables the power supply of electrical equipment items operated in intrinsically safe systems within hazardous locations which are susceptible to firedamp. The power supply unit NG3-12ib provides protection according to type EEx m [ib] I.
