7. Current sensor.
The main controller board also receives the +12 VDC low current from the power supply.
The main power supply operates from an 180 - 264 VAC, 47-63 Hz power source.
The secondary power supply provides multiple outputs for operating the L-Band/C-Band up-
converter and the power amplifier modules.
To prevent unwanted noise from entering the SSPB, a line filter is connected between the AC input
connector and the main power supply. The overall typical power consumption, at the rated RF
output power, is approximately 400 Watts.
3.7 COOLING SYSTEM
The cooling system for the SSPB consists of four cooling fans. Two fans are mounted at the front
panel and the other two at the rear panel (see
Figure 1 at page 9).
The Varifan power supplies p 48 VDC voltages (variable between 11 and 60 VDC,
temperature dependent voltages) for operating the four cooling fans. The Varifan power supplies
are configured for +12 VDC input voltage operation.
3.8 FRONT PANEL
The front panel provides for the user, LOCAL monitoring and control of the SSPB. The front
panel contains an ON/OFF circuit breaker, six pushbuttons, six LEDs and a vacuum florescent
display (VFD).
TABLE 1 at page 15 lists and describes the front panel controls and indications.
Figure 3 at page 16 shows the front panel outline.
