APPLICATION DESCRIPTION
Three different spike durations are provided: 0.15 µS, 5.0 µS, and 10.0 µS. The pulse shape approximates the curve of Figure 1 in MIL-STD- 462. The amplitude of the spike voltage is fully adjustable and is displayed on a digital meter. Two sets of output terminals allow either parallel or series injection into the power line. Series injection is used on AC lines. Parallel injection is used on DC lines. The output winding used for series injection can carry 25 A of power current. The output terminals are isolated from the chassis and the power cord. The repetition rate of the spike can be adjusted with a panel control to any rate from 0.5 to 50 pulse per second. A single pulse can be injected with the aid of a panel-mounted pushbutton. All functions are selected by pushbuttons which are lighted when activated. The Solar Model 8282-1 Transient Pulse Generator provides up to 600 V peak amplitude for each of the 0.15, 5.0 and 10.0 µS spikes. The output voltage rises steeply to peak amplitude as adjusted by the panel control, then falls exponentially to cross through zero at the duration of 0.15, 5.0, or 10.0 µS as selected by pushbuttons. The voltage falls below zero and "rings" for a period determined by the inductance in the output circuit or the load.
With series injection on 50, 60 or 400 Hz power lines, the spike can be applied to either the positive or negative half cycle of the power frequency sine wave. The spike can be adjusted to fall on the power sine wave from 0º to 360º . For non-synchronous injection,
the repetition rate can be adjusted from 0.5 to 50 p.p.s. Two methods of remote triggering are provided. One method requires the application of 24 V DC to trigger the pulse at rates determined by an external switch up to 50 pulse per second. The second method requires the application of a square wave which can be used to trigger the spike up to 50 pulse per second for the 0.15 µS spike and up to 1000 pulse per second for the 5.0 and 10.0 µS spikes. This latter feature can be used to trigger the spike in sync with some function within the equipment under test.
