The board provides stabilised power supply ±15V for control circuits and protection circuits of traction motor, current sensors of 81-717/81-714 metro car drive. Control circuits provide stabilisation of traction motor armature current in different modes of traction drive operation. Protection circuits provide attenuation of the traction motor field to the minimum value when the traction current exceeds the maximum value of 600A.
The board is installed in the control unit of the traction motors excitation current regulator type DRP300/300.
The board is a printed circuit board.
