Board
A1676W Wiener PS Controller characteristics:
• The Model A1676W is a board, designed for the SY1527/2527/3527 System family, whichallows to control up to 8 W-IE-NE-R Mod. PL500 power supplies via CANBUS. The boardis single-width.
• The A1676W can handle 64 PS channels, since each PL500 can house up to 8 channels. All the channels are seen as Caen channels.
• The board allows to control the PS channels through a complete set of programmableparameters, such as output voltage, current limits, etc.

Measure of the Channel Tripoff Measure of the Channel Tripoff Response Time (TResponse Time (TRR))
A CH TRIPOFF has been induced (OVC on Ch#1), we measured the switch OFF time of the single channel (reaction time).

In case of CANbus controller power cut (SY1527 power cut) , an Interlock signal switches Off the connected PS’s.Recovering of the settings after a power cut is guaranteed since all the values are written in the E2PROM of the A1676A.

In case of CANbus disconnection, the occurrence of an over current can be limited by setting each channel Current Limit’ equal to the OVC. Is now under study the activation (via PVSS) of the the Interlock line to switch Off in a selective way the “unplugged” PS.

ConclusionsConclusions
• The PL500F8 technical specifications fits the LV sector requirements but the control features.
• The prototype of the new project CAEN –WIENER (A1676W), with single channel ON⁄OFF, grouping,…, is now running! The test results on the reaction time, are in agreement with the expectations and are very encouraging!!
• The PVSS HMPID LV Control has been updated taking into account the new PS features
