1 kW Amplifier Overheating Protection
Special circuits protect the 1 kW amplifier against overheating. If the temperature is too high to
enable full-power operation, the output power is automatically halved, until the temperature returns
to normal.
However, if the temperature exceeds the maximum allowed limit and damage may be caused, the
protection circuits are activated and bypass the amplifier.
Imbalance Protection
When a fault, power failure or other type of failure prevents normal operation of one or more of its
internal amplification modules, the 1 kW amplifier is automatically bypassed.
PS Unit
The PS unit, type YM-02-670B, is manufactured by Lambda Inc. See its manufacturer’s manual for
complete information.
The unit is a 110/220 VAC, 50/60 Hz AC-powered power supply contained in a compact chassis
suitable for installation in 19” racks. The AC input voltage range is automatically switched between
110 and 220 VAC, and therefore the equipment can be used in the United States of America as well
as in other countries. Internal cooling fans enable operation over a wide range of temperatures.
The PS unit includes two independent power supply subsystems, each providing +45V to two of the
four amplification modules in the 1 kW amplifier. Protection circuits monitor each output, and
provide indications on front panel indicators in case the output voltages deviate by more than 25%
from the nominal value; if an output voltage increases beyond the maximum limit, the corresponding
power supply subsystem is turned off, to prevent damage to the 1 kW amplifier.
