5.3.4.4 Power Supplies
The Fourier300 Console has two AC power supplies.
• PSU 1: Input 90 – 250 Vac, Output: +5V, ±12V and +24Vdc (+standby voltage)
•VTU
•Fans
• Ethernet Hub
• Preamplifiers
PSU 2: Input 90 – 250 Vac, Output: +28Vdc, 20 A
• Main Board
•Lock Board
• Shim Boards
• Transmitters
• GAB/Backplane
When the mains switch on the rear panel is switched on, the console first goes into stand
by which is indicated by a blinking ON/OFF switch. Pressing the ON-OFF Switch then
provides both PSU1 and PSU2 via inhibit signals provided by the Power ON/OFF Con-
trol Board which is located close to the ON/OFF switch.
PSU1 is fused with 4A slow blowing fuses. The power consumption of the console is
approx 300 W.
For details of how the power is distributed to the units see the wiring schedule in the
appendix.
