This range of power supplies are miniature versions of the HP family giving up to 1kV, 2.5kV, or 3kV, at 2W. The units, which are programmable by a 0 to +10 volt signal, are intended to be mounted on a printed circuit board and offer high stability together with low drift. They use high frequency pulse width modulated switching techniques in conjunction with a ferrite step-up transformer to control the output voltage.
Applications include powering photomultiplier tubes, and electron multipliers in scientific and other instruments.
We manufacture a number of special versions of these units and would be pleased to discuss your volume application with you.
