1.0 GENERAL DESCRIPTION
The DEI PVX-4140 B is a solid-state high-voltage pulser designed to drive capacitive
loads such as grids and deflection, reflection and acceleration plates.
The instrument features an output voltage swing of up to 3500 V, peak current of up
to 25 A, and continuous current of up to 0.1 A. It can output DC as well as very flat
voltage pulses into a capacitive load.
The PVX-4140 B generates single-ended output pulses from ground to +3500 V or
from ground to -3500 V; it can also generate pulses originating from a voltage offset
from ground. The offset can range from -3500 V to +3500 V with a maximum
differential of 3500 V.
2.0 SPECIFICATIONS
Reference the PVX-4140 B datasheet on the website for the specifications:
3.0 SAFETY
The high voltage capability of this instrument dictates caution when operating it. The
following is a summary of general safety precautions that must be observed during all
phases of operation of the PVX-4140 B.
WARNING
•
Risk of lethal electric shock. Do not touch the output or load while the PVX-
4140 B is operating. This instrument produces LETHAL levels of electric
current at its output.
•
DO NOT OPERATE THIS INSTRUMENT UNLESS ANOTHER PERSON,
CAPABLE OF RENDERING FIRST AID OR RESUSCITATION, IS PRESENT.
•
SAFE AND PROPER OPERATION OF THIS INSTRUMENT IS THE
RESPONSIBILITY OF THE USER.
•
The cover should NEVER be removed. There are NO user-serviceable items
inside.
•
Always turn the high voltage power supplies and the PVX-4140 B OFF prior to
working with the load or input and output cables.
•
Do not remove the input or output cables while the instrument is in operation. Never
short-circuit the output. Failure to observe these precautions can result in potential
electric shock to personnel, arcing, and damage to the connectors and the
instrument.
