PS-2 & PS-2/LV

The PS-2 and PS-2/LV are Sutter PMT power supplies sold with the Sutter MOM®. They are also available to those who need dual power supplies for either their own scanning microscope or other projects that need PMT power supplies. The PS-2 is a dual high voltage supply specifically designed to be used with the Hamamatsu R6357 multi alkali PMT but applicable to other similar PMTs. The PS-2/LV was originally designed to be used with the Hamamatsu H10770PA-40 PMT Module, but is applicable to many other similar PMT modules that have the high voltage supply built into the device and only require a low voltage supply and a control voltage to set gain.

The PS-2 and PS-2/LV have additional outputs for running preamplifiers and other associated circuitry. Both are dual supplies with discrete on/off switches, gain controls and voltage displays for the two PMTs attached. These two models are manually controlled, which is convenient for those designing their own scopes; there is no need to worry about PC control of various parameters. Just plug in the PMT and power up!

To keep generated noise at a minimum, linear power supplies are used to generate all low voltages and to power the high voltage supplies.
