Power backplanes aid prototyping
Schroff has expanded its range of power backplanes.
Schroff has expanded its range of power backplanes The boards can be fitted anywhere within the backplane area, and are generally used as adapters between 19in power supplies and the backplane

Schroff, one of the industry's leading manufacturers of CompactPCI Microcomputer Packaging solutions, has unveiled a complementary range of 19" power supplies.
Cut-down prices for CPCI
Europac Integral offers all the benefits of a standard CPCI system including high stability, robustness and EMC shielding but at a far-reduced cost.
They offer significant benefits to users involved in prototype and small-sized production, because the costly development and manufacture of application-specific backplanes with integral power supply is no longer necessary.
The new model with P47 connector now provides CompactPCI system developers with a simple, quick and economic means of connecting PICMG 2.11-compliant power supplies, such as Schroff's maxpowerPRO unit, to CompactPCI backplanes.
The new power backplane features a particularly high degree of modularity.
It supports the connection of up to four power supply units in parallel, with separable fault signals for failure and derating of outputs.
This means that a higher-level monitoring unit, such as Schroff's Chassis Monitoring Module (CMM), can perform logical operations on the signals before they are forwarded to the CPU.
This is an essential requirement for studying at the prototype stage the monitoring of redundant power supplies in high-availability systems.
Of course it is physically possible to connect the fault signals in parallel, but technically this is not compatible with redundant operation of several power supplies.
The System Management Bus as specified in PICMG 2.09 is integrated on the board, so that together with the definable geographical address of each slot, information on the status of each power supply in the system can be monitored at a higher level.
Users are thus able to locate weak points well in advance.
