Analytical Measuring Devices

Analytical measuring devices require power supplies with high accuracy, stability and low noise performance in compact form factors. Reliable high voltage power supplies are pivotal to mass spectrometry, scanning electron microscopy, electron beam lithography, gel and capillary electrophoresis, plus many other analytical applications.

• High voltage modules
• Smart power high voltage DC-DC power supplies
• High precision power supplies
• High voltage amplifiers
• High voltage biasing power supplies

Grid

PPM Power can provide products for high voltage electric power transmission networks. Electric power systems have evolved with interconnections of renewable energy and grid simulation is important for verification tests. High voltage AC breakers are needed to strengthen the power grid and improve flexibility to cope with changing power demand.

• Ultra high power resistors
• High power semiconductor modules
• Solid state breakers
• High voltage probes
• Programmable AC power sources

Subsea

Subsea and shipboard power supplies are used to supply power to compressors, pumps and other electrical components used in offshore, onshore and shipboard applications, in both shallow and deep water subsea installations. They have strict requirements for harmonics and are often used in harsh environments. The latest power conversion technology enables an array of offshore instruments to provide continuous acquisition of real-time data in one of the world’s most inaccessible, difficult-to-study environments over thousands of kilometres. Other components used in subsea applications include:

• High voltage switching modules for power control
• High voltage diodes
• DC circuit breakers for shipboard power
• High power DC/DC converters.

Particle Accelerators

The right magnet power unit delivers high-precision current coupled with excellent long-term stability and high dynamism. The fast and ultra-precise control and current measurement needed for this require specialist expertise and the right choice of components. PPM Power supplies a wide range of power supplies for magnet applications, as well as other products for the particle accelerators market including:

• Genesys programmable power supplies
• High precision power supplies
• Power supplies for magnets
• Capacitor chargers for Linear Accelerators (LINACs)
• Custom solutions and modulators for LINACs
• Behlke switches for muon sweeping or beam choppers
• Ultra high precision current transducers for research purposes
• High voltage and high accuracy probes.
