High Voltage Switching Systems
HXV Series
-
HXV products are high voltage systems intened for Hi-pot / IR or High voltage switching. They can be configured to drive from 32 to 128 switch points per chassis and can be configured as multiplexer (1xN) or Matrix (NxM) configurations. Stand HXV chassis are used for signals up to 5000 VAC rms ( 7400 V peak ) and can carry up to 5 amps of current. Custom systems can be built up to 25KV. Most of the modules used in these systems are 1xN multiplexers or 2x4 matrix modules that can be combined to form larger multiplexers or matrices. Connector options for standard HXV include 5 way banaba jacks / binding posts, Shrouded Banana Jacks or SHV ( High voltage BNC) if you need to use a high voltage cable with a grounded shield for safety applications. Control options include 10/100BaseT Ethernet LAN, RS232, GPIB or optional manual control. Standard HXV systems use high voltage reed relays. Custom HXV systems up to 25KV use application specific relays and connectors from a variety of vendors based on required specifications.

SCSI CABLE TESTER
ST123
-
Continuity tests alone are not sufficient to qualify SCSI cable assemblies. Proper testing of SCSI cables must include a test for correct connection of twisted pairs and shielding. Continuity tests check only that wires are making connections on both ends of a cable.Twisted pairs in the cable must be matched with the correct SCSI signal pairs - otherwise, it is possible to have a SCSI signal (signal and ground pair) placed on wires that are not in the same physical twisted pair (see diagram at right). This will cause crosstalk with resultant SCSI errors.
