Matsusada Wein Filter Power supplies 2018
This page describes the implementation of the Matsusada 0-30kV power supplies for driving the Wein filter high voltage plates.
We attempt to purchase systems completely off-the-shelf as much as possible for this application. It may look like something of a rats nest of serial, fiber optic, and interface cables, but that is how it comes from Matsusada. The serial cable from the Digiport server does not go directly to the power supplies. Instead it goes to a serial to optical converter box. The reason behind converting to optical is so the DAQ system can be galvanically isolated from the power supplies. This ensures that any noise on the digital side is not transferred to the analog outputs, and any noise that might be created on the analog outputs will not affect the digital side.
The optical-GPIB units communicate independently of the power supplies, not just a pass-through. They continue communicating, even sending status information when the supplies are off/disconnected. The remote/local status relates to the units, not the supplies.
The first five DIP switch settings on each unit sets the address. Switch 8 means upstream link (first in chain). Unit 1 should set switches 1 & 8, unit 2 should set switch 2. Our setup is most like page 9 of the CO series manual.
