XL-Desk is fitted with a 12V 33A auto-sensing universal power supply which will function at any voltage from 100 to 230 volts ±10% without adjustment.
The XL-Desk power consumption is <300 Watts
The power supply is SSL part 629732X6 (37149FCC SMPS UPFC 400W 12V 33A EFORE DDP400-US12-SC).
This 12V power feeds two power distribution boards, parts 62A014X1, to generate the voltages for the rest of the console:
- The first (lower) 014X1 provides power rails to the channels and faders. Those are ±15Vdc, 3.3Vdc, and 5Vdc. This card sits underneath the 016X1 FPGA card.
- The second (upper) 014X1 provides power to the master panel and 500 series rack only. ±16Vdc.
- Link LK1 defines their function and must be matched when replacing.
The power supply feeds the three 12V fans directly so fan operation is a good indicator of PSU operation.
