The Data Design Minicrate Model 1000 provides a cost effective solution for small CAMAC based instrument configurations. The Minicrate incorporates high power switching power supplies containing all standard CAMAC voltages as well as the often used ▒12 V power. Both short circuit protection and overvoltage shutdown circuitry are incorporated in the design of the power supply to guard against accidental damage to modules. Cooling for the thermally isolated power supply compartment is provided by its own dedicated fan. The enclosure is all aluminum and has two stage, integral, RFI line filters which reduce its susceptibility to conducted as well as radiated noise. The power supply has additional filtering allowing many low signal level modules to be used. Due to the side location of the power supply, the case depth is less than 16 inches.




Number of Module Positions: Eleven (right two positions required for crate controller).

Dataway Interface: As per IEEE 583-1975.
