The LS Series sets a new standard for high voltage precision and
stability. By optimising the Low Stress™ technologies used
in our leading 10 Watt HP Series for 1 Watt applications, the new
LS Series has less than 1ppm ripple, 10ppm/°C temperature coefficient,
and 50ppm drift/hr throughout the range. Each of the units includes
a differential control input.
To take full advantage of the performance available from the
LS Range, they are initially only being made available to our OEM
customers as application specific, custom optimised, modules.
All units are short circuit proof and use proven techniques to
drive a high frequency oscillator and ferrite high voltage step-up
transformer. These advanced power supplies build on Applied Kilovolts'
legendary reputation for reliability, being constructed from conservatively
rated components with their reliability further enhanced by information
gained over many years of field operation.
Available as positive and negative units up to 50kV, and electrically
reversible at voltages up to 30kV.
Please see the HPZ range for zero crossing
reversible (bi-polar) units.
We manufacture a large number of customized OEM versions and would
be pleased to discuss your application with you.
