BUM-1.2 power amplification block

The BUM-1.2 power amplification block is intended for control by VS1,VS2 power thyristors and for providing galvanic isolation of the control system from high-voltage electric drive part.
The BUM-1.2 block enters into a control system of the tractive electric drive of various modifications of "BelAZ" mining dump trucks. 
The BUM-1.2 block correspond to ТY BY 101269853.001-2013
