The MNX Series is the result of Spellman’s exceptional
high voltage packaging and surface mount fabrication
techniques, coupled with its proprietary encapsulation
technology producing this ultra compact-sized OEM 50
Watt X-ray generator module.
The MNX Series is designed to power grounded cathode
X-ray tubes from a variety of well known manufacturers. It
features a 0 to 50kV high voltage output, and up to 2mA
of emission current limited to 50 Watts, operating from a
+24Vdc input. The MNX utilizes a closed loop filamentry
beam control circuit to provide a highly regulated beam
current. The ground referenced low noise dc filament
supply operates between 0.3 and 3.5 amps. Offering tight
regulation, high stability and low ripple, the MNX provides
users both local and remote analog control to set beam
voltage, emission current and filament current limit. An
optional USB, RS232 or ethernet interface is available.
TYPICAL APPLICATIONS
Powering grounded cathode X-ray tubes from
Kevex, Oxford, RTW, Superior, Varian and Trufocus.
OPTIONS
XCC XRM Compatible HV Cable
SIC Standard Interface Controller
(Ethenet, USB & RS232)
