There are two power supplies in this SSPB. The power supplies provide +12 VDC high current
and a – 9 VDC low current to the Up-Converter and to the High Power Amplifier (HPA). One of
the power supplies provides +5V delivered to the RS-232 Serial Interface for Hand Held
Terminal supplying. The power supplies are configured for operation from 198-264 V AC,
single phase, 47-63 Hz.
The fan is configured for 220 VAC operation, supplied by a speed controller to allow for a
variable (temperature dependent) rotation speed.
The overall power consumption, at rated RF output power, is 1500 W.
