 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.
