High Stability & Ultra-Low Noise High-Voltage Power Supply
The J4 and J6 series are high-performance power supplies designed for photomultiplier tubes (PMTs), ideal for applications in mass spectrometry and scintillation-type radiation detectors.
- J4 series
-
The J4 series provides up to 4 W of power with ultra-low ripple noise (2 mVp-p). It is suitable for PMTs, phototubes, GM tubes, proportional counters, and solid-state detectors.
- J6 series
-
The J6 series offers higher power output (6 W) with low noise performance (5 mVp-p). Like the J4 series, it supports a wide range of detectors including phototubes, GM tubes, and semiconductor radiation detectors.

How to Order
J4-(Output Voltage)(Polarity)[-L][X][Input voltage][Output connector]
(Output voltage) Select from 0.5/1/1.5/2/3/5 (unit: kV)
(Polarity) Select from P/N. P: Positive, N: Negative
[-L] is the symbol to be added when adding an option or selecting the LX/L15/LX15 model.
Add it when adding an option or selecting the LX model.
[X] Add when changing to a card edge connector and base plate model.
[Input voltage] Add "15" when changing the input voltage range from ±12 Vdc to ±18 Vdc.
[Output connector] can be added from MH/SH. The tip of the output cable can be changed to MH: MHV connector, and SH: SHV connector, respectively.
<Example> J4-1P-L15, J4-1.5N-LMH, J4-2P-LX15, J4-3N-LXSH, J4-5P-LX15MH
J6: When ordering, add Option No. in the following order by alphabet to Model No.
<Example> J6-1.5P-LMH
