FX 950 T
General Description
FX950T is a stabilized ferro-resonant power supply unit,
with a fixed output, for a 3kW powered magnetron.
The power supply unit must be connected to the
2 x 400V/50Hz electric network without neutral, and is
provided in “open frame ” version to be assembled in the
electrical panel.
General Information
The FX 950 T power supply unit is in compliance
with the EN 61010-1 (=CEI 66-5) European Standard
approved by Cenelec on 9/3/1993. As provided by
this standard, the equipment must be installed and
used exclusively by qualified personnel instructed on
the precautions and operating mode. The generator, if
correctly installed, is in compliance with the expected
radio noise limits for Group 2, Class A equipment
provided by the EN 55011 regulation.
CAUTION!
FX 950 T is powered through the mains: read this
manual carefully before installing the equipment.
Make sure that the electric connection and the
utilisation are correct.
Failure to comply with the instructions implies serious
risks for the personnel in charge of the equipment
utilisation, as well as the possibility to cause
equipment breakdowns.
