Power supply unit BP-RN-36/127-24 is a stabilised 24V DC voltage source with output current limitation, protection against overload, short-circuit currents and overvoltage. It is used for conversion of 36V mains supply voltage (input voltage range: 14 ~ 50 VAC) or 127V mains supply voltage (input voltage range: 85 ~ 264VAC), which is supplied to the equipment of mine automation, signalling and communication systems.
The BP-PN consists of a metal case, inside of which there are two compartments: hardware and cable glands. At the bottom of the hardware compartment, the network converters are fixed from inside, which are placed in a separate metal compartment and filled with compound to protect live parts from water ingress.
The outputs from the network converters of the hardware compartment are led to the switching module with terminal connectors of the cable gland compartment, which are available for use by the operating service during installation and mounting.
