1. INTRODUCTION
1.1.
Device Classification
The device described herein is a Security Radiological Power Supply. Using Annex H of the
“Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory
Use”, EN61010-1, we have concluded that the model XRV SERIES is classified as a Class I
device. Based on our analysis, the device makes no protection against the ingress of water.
This device is designed for continuous operation. The device is required to be connected to
protective earth ground.
1.2.
Intended Use
The XRV SERIES is a negative output 3kW or bipolar output 4.5KW high voltage switching
power supply which incorporates the latest in high frequency, high power switching
technology used to drive an x-ray tube, as well as to serve as a source of a reliable high
voltage for other type of loads. The Power Supply operates from 180-264 Vac 50/60Hz
power line. The Power Supply is air-cooled with 4.7 ” fan located on the Rear Panel. Air is
pulled in through filtered slots in front of the unit and exits in the rear of the HVPS Enclosure.
The Power Supply is designed to meet the FDA safety requirements Title 21, part 1020,
section 20 (21 CFR 1020.40 Cabinet X-ray Systems) as used in the NDT application.
1.3.
Interferences Between Equipment
The device was designed and manufactured to minimize electromagnetic or other
interferences. Tests have been performed to evaluate potential risks that could originate
from the device itself or the surrounding environment. All test results were acceptable, and
there has been no evidence of interference in its intended application.
1.4.
Device Description
The Unit provides a high voltage potential for the cathode X-ray tube with two separate
filament supplies. There are two basic power supply sections for this purpose:
(Single-ended version) negative or positive high voltage output, continuously
programmable from 0 to Maximum kV DC and with a maximum operating rated specified
current.
(Bipolar version) positive and negative high voltage outputs, continuously programmable
from 0 to Maximum kV DC and with a maximum operating rated specified current.
Dual DC X-ray tube filament supply, floating at the high voltage potential, programmable
from 0 to Maximum ADC. User selectable filament supply has two separate outputs, one
for the small filament and another large filament.
