The 6063 rackframe is a 19” wide, 3U high unit offering an extensive mix and match
capability for up to 12 modules.
Notable characteristics of the rackframe are:
•versatility to accommodate different modules
•dual mains transformers
•robust construction
•removable door
•anti-static earthing point
It has the flexibility to accommodate different modules by allowing various
motherboard sections to be installed to suit specific applications. Two card slots are
designated for the standard range of modules, the remaining ten slots are
configurable in two, five slot motherboard sections to cater for further standard type
modules, digital video converters, or fibre optic interfaces.
There are three different types of Pro-Bel modules that can be fitted in the 6063
frame:
•conventional modules, using a type 1 motherboard
•digital video ADC/DAC, using a type 2 motherboard
•fibre optic interfaces, using a type 3 motherboard
The type 1 motherboard accommodates five cards, together with their relevant rear
connector assemblies.
Up to four Digital video ADC and DAC converter cards are catered for by the type 2
motherboard section. It is available as a complete unit, comprising a motherboard
section, a regulator card and a termination assembly.
The fibre optic interface motherboard section, type 3, allows five of these cards to be
accommodated in the rackframe.
Two mains transformers are fitted as standard, giving automatic supply redundancy.
These transformers provide twin ac power rails along the motherboard, with each
card locally rectifying and regulating from these to suit its individual requirements.
This arrangement not only removes the PSU as a major point of failure, but
additionally distributes the heat dissipation evenly across the frame.
