5-7-2-1 General description (cont’d)
Power from the wall outlet (100 to 240 VAC, 50/60 Hz) is connected to the Main Power Supply. The
Main Power Supply delivers the needed voltages to the rest of the LOGIQ E9:
• Internal Printer (110 VAC)
• Front End Rack (DC power with several voltages)
• Front End Rack (TSV1 and TSV2 for the transmitters)
• Front End Rack (PMXVOUT for the probe channel multiplexers)
• Back End Processor
An inrush current limiter reduce the peak input current when the LOGIQ E9 is switched on. An EMI filter
helps to reduce EMI to acceptable levels.
The mains cord has plugs in both ends. A female plug connects to the scanner and a male plug to the
wall outlet.
Fuses are located inside the power supply (only to be replaced by the manufacturer).
