Parker 990A modular

Description
The Model 990 Series Magnetreaters® are highly accurate, pulse type, ringing
demagnetizers (also called treaters) for the controlled stabilization of permanent magnets
and permanent magnet assemblies. Regardless of line voltage stability they provide a
controlled output through continuous pulse amplitude regulation. Treating voltage is
variable from 0 to 600 VDC. Additional energy can be added to the Model 990 Series by
interconnecting a Model 992 Energy Booster. The energy level is increased from 18 to 36
watt-seconds. With this option treating coils will produce higher demagnetizing fields
and lower ringing frequencies, which can provide greater field penetration in some
applications.
Model 990A
The Model 990A Magnetreater® is designed for manual control of treating or it can be
equipped with the optional IEEE-488 interface module and D/A reference generator
module for computer control. The unit has two output controls for manually adjusting the
treating pulse output, a pulse rate control, and a series of front panel lights to indicate
system status.
