Notes:

  1. B67559_02 had one event where its voltage exceeded the 3 Volt range (used by the test program, not the EPICS software) around the demand voltage, going up to -2904 V from -2900 V.  As this event did not cause a trip of any kind and was never repeated, the module was passed.
  2. These modules were tested with an operating voltage of -2900 V, since, with the loads we have, operations at -3000 V bring the current very close to the -12000 microamp current trip, and thus can cause infrequent current trips.

Notes:

  1. B50953, the prototype of this module type, yields a current that is approxiamately 250 microamps higher than other channels connected to the same loads at the same voltages.  It is being set aside.
  2. Channel B67563_02 is flawed; upon being enabled, its voltage automatically rises to about -2900V, regardless of the Demand voltage.  Voltage errors and Supply limit violation trips usually follow this.  It also yields a much lower current than normal.  This module is being set aside as well.
  3. Due to the above problems, the modules were tested at an operating voltage of -2900V.
