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.
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.
