The BP-RV-380/660 power supply unit is a stabilised DC voltage source, with output current limitation and short-circuit protection, used to convert 380/660V voltage into 24V DC voltage, which is supplied to the equipment of mine automation, signalling and communication systems. BP-RV is a construction consisting of a protective shell made of steel sheet and two connection blocks made in accordance with the requirements for flameproof enclosures.The input circuit connection block has two chambers under the cover, one of which contains terminals for connection of AC supply voltage ~380V, the other - terminals for connection of AC supply voltage ~660V, in a separate compartment - fuses for output circuits.
In the output circuit connection block under the cover there are two chambers, each of which contains terminals for connection of 24V DC voltage equipment.
