Low Voltage Power Supply Project

ELMB Mother Board

The ELMB Motherboard and ELMB module inside the LVBOX are connected to eight DC/DC converters and permit a remote PC monitoring of their behavioral parameters (temperatures, Iin, Iout, Vin, Vout, DIG and MB side sense line voltages). The ELMB_MB is also a control board to set the Vout trimming of all bricks. The Start-up sequence of an LVBOX is carried out in 3 groups of bricks. The HV or DIG side brick group shutdowns are triggered by most critical power lines: -5VMB, +15VMB, and -15VHV bricks.
