MP Series

Miniature High Voltage Modules to 3kV

MP001, MP2.5, MP003

Applications: Photomultiplier tubes, Lens & bias supplies, Test Equipment

  • 2W programmable o/p Voltage
  • Size 80mm x 55mm x 20mm (1kV)
  • High stability, low ripple
  • High frequency switch mode
  • Short circuit and flashover proof
  • 0-10 volt programming
  • 24 hour burn in

This range of power supplies are a miniature version of the HP family giving up to 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.
