High Voltage Power Supply for Photomultiplier Tube (PMT)

  • Max Voltage: 5kV
  • Max Current: 2mA
  • Max Ripple: 15 mVp-p

Power supply for preamplifier are integrated.

EP series is high-performance high voltage power supplies for photomultiplier tube (PMT), Electron multiplier application. The ultra-compact size of just 8.35 inches/212 mm in width. Integrated High Voltage power supply and power supply for preamplifier ±15 V and ±5 V. The ultra-low ripple noise of as low as 15 mVp-p (High Voltage output part) is suitable for PMT and various other applications. In addition, various digital control is also possible by selecting the -LGob option.

Options

-LGob

Optical Interface Board
With optical communication, isolation control is performed. As complete isolation is performed by means of optical fiber, this enables advance prevention of erroneous operation involved with transient phenomenon caused by surges, inductive lightning, external noise, etc.

  • -LGob: Optical interface board + optical cable 2 meters
  • -LGob(Fc5): Optical interface board + optical cable 5 meters
  • -LGob(Fc10): Optical interface board + optical cable 10 meters
  • -LGob(Fc20): Optical interface board + optical cable 20 meters
  • -LGob(Fc40): Optical interface board + optical cable 40 meters

Select the optional optical interface board (-LGob) when using this high voltage power supply under the following conditions.

  • Noisy environment including factories (Example: Motors or coils are used near power supplies and loads).
  • Using with high voltage floating (more than 250 V).
  • Installation distance of 2 meters or more between the high voltage power supply and a controller such as a computer, laptop, or Programmable Logic Controller (PLC).
