Product description
The DT2500 intrinsically safe output power supplies deliver galvanically isolated, IS power for devices installed in Zone 1 potentially explosive atmospheres. The units are certified II (2)G [Ex ib Gb] IIC or II (2)G [Ex ib Gb] IIB (certification: BKI 15 ATEX 0023 X). A front-panel potentiometer allows adjustment of the output voltage within the ranges indicated in the type designation. The design supports flexible adaptation to the user’s requirements regarding gas group (IIC or IIB) and the Ci/ Li parameters of the connected apparatus.
