The large area scintillator detector array for detecting charged particles and neutrons at RIBLL (LASCAR-Large Area Scattering Chamber at RIBLL) consists of 8 scintillator blocks (500 mm×500 mm×80 mm). Each block has 49 photomultipliers (PMTs) for the centroid readout. A multi-channel control system was developed to control the high voltage power supplies of 392 PMTs. The high voltage power supply is based on a +12 V
