MODEL 7054-1 SPIKE GENERATOR
600 volts
for conducted transient susceptibility testing up to 600 volts peak
For those who have graduated from the 50 volt
and 100 volt spike susceptibility category, we
offer this high-power 600 volt transient generator.
The Model 7054-1 delivers over 300 kw into
low resistance loads. It has the flexibility and
capability of the previous models, including
the ability to shift the transient in phase to any
position on the sine wave of the a.c. line feeding
the test sample.The amplitude and the repetition
rate are adjustable.
APPLICATION
The Model 7054-1 Spike Generator was
especially designed for screen room use in
applying high voltage transients at power line
inputs to electronic equipment. The adjustable
amplitude makes it possible to determine
the threshold of susceptibility to spikes
appearing on the power line. The Model 7054-1
may be used for performing tests per
Method CS06 of MIL-STD-462, Method 5006.1 of
MIL-STD-826A, RTCA D0160D (with impedance
matching transformer) various missile specifications and others.
DESCRIPTION
The peak amplitude of the Model 7054-1 Spike
Generator is adjustable from 10 volts to over 600
volts into 5 ohms. The source impedance is less
than 0.5 ohm. The transient shape approximates
the curve given in Figure 19 of MIL-STD-462.
Less than one microsecond rise time and
approximately 10 microseconds fall time.
On 50, 60 or 400 Hz power lines the transient
can be applied in a periodic manner to the
negative or the positive half-cycle of the power
frequency. The transient’s relation to the sine
wave may be adjusted in phase from 0° to 360°.
For non-synchronous injection on either a.c. or
d.c. lines,the repetition rate can be adjusted from
0.8 p.p.s. to 10 p.p.s. Single transients can be
applied with the pushbutton on the panel.
Two sets of output terminals allow either parallel
or series injection into the power line. Series
injection may be used on d.c. and a.c. lines.
Parallel injection is used on d.c. lines only.The
output winding used for series injection can carry
25 amperes of power current. The output
terminals are isolated from the chassis and the
power cord.
