The LT Series builds on the new standard for high voltage precision
and stability set by the LS 1 W family.
By optimising the Low Stress™ technologies pioneered in the
LS family, the LT Series provides 3W o/p capability, but still has
less than 2ppm ripple, 10ppm/°C temperature coefficient, and
75ppm drift/hr throughout the range, while retaining the same LS
case dimensions. Each of the units includes a differential control
input.
To take full advantage of the performance available from the
LT 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 or negative up to 50kV, and electrically
reversible at voltages up to 30kV.
We manufacture a large number of customized OEM versions and would
be pleased to discuss your application with you.
