Atec CPI-VZK-6901J1 User Manual

Split Mount

The split mount configuration provides for direct
feed mounting to minimize waveguide RF losses.
The power supply maintains the convenience of
a rack mounted unit with built-in monitors and
controls located up to 12 meters away.

Versatile

Ultra wide-band, automatic fault recycle, user­friendly microprocessor-controlled logic with
integrated RS-422/485 computer interface.

IEEE interface and other options available.

Easy to Maintain

Automatic sequencing of voltages and filament
time delay. The power supply HV outputs to the
appropriate TWT label voltages are automatically
set with an integrated, individualized TWT
personality interface module.
