RA 55 
RA 55 accommodates nine (9) plug-in MST
power supplies in a standard 19-inch wide rack mountable housing. Each power module can produce up to 200 watts, so that the total for
the rack can be 1800 watts. RA 55's leftmost slot can be used to hold an interface,
MST 488-27, that will allow the
remaining eight (8) MST modules to be fully programmed via the IEEE 488.2 instrumentation bus. The rack has two a-c input
connectors to allow the load to be distributed over two mains circuits. The a-c is distributed internally to the plug-in MST
power supplies.

controller
The rear of RA 55 has individual d-c output connections for each MST power module and a D-type serial bus connector for the
BITBUS connection to the power modules. The MST modules plug in individually from the front and will current-share for
redundancy combinations.
RA 55 is CE Marked per the Low Voltage Directive (LVD), EN61010-1 in accordance with the Conditions of Conformance.
Size: 19"W x 7"H x 20.89"D
CA 400
CA 400 is similar to the RA 55 except it is a housing which accommodates five (5) plug-in MST
power supplies and can be used to mount MST's in non-standard racks. Each power module can produce up to 200 watts, so that the total for the housing can be 1800 watts. CA 400's leftmost slot can be used to hold an interface,
MST 488-27, that will allow the
remaining four (4) MST modules to be fully programmed via the IEEE 488.2 instrumentation bus. The a-c is distributed internally to the plug-in MST power supplies via an a-c input connector.
CA 400 is CE Marked per the Low Voltage Directive (LVD), EN61010-1 in accordance with the Conditions of Conformance.
RA 56
RA 56 provides rack mounting for a single
DPS bench style power supply. This allows them to be integrated into systems
applications where their RS 232 control and communications ability may be exploited.
Size: 19"W x 5.25"H x 8.53"D
