Intrinsically safe Power supply type NSB3-xxx/5Via
Power supply type NSB3-xxx/5Via is intended for use in mining applications. It will convert an AC supply voltage into a stabilized and regulated intrinsically safe source for supplying power to approved electronic control devices.
Power supply NSB3-xxx/5Via provides two 5VDC intrinsically safe outputs, capable to source up to 1100 mA. Power supply also provide 4-20 mA output signal to monitor battery state of charge and potential-free changeover relay to indicate mains fuse failure. In the case of power supply cut, automatic battery backup is provided (min 6hrs).
