  • Instrumentation chassis with single output AC to DC power supply and DC to DC switching regulators
    Patent number: 10840701
    Abstract: A modular instrumentation chassis includes a backplane PCB; multiple slots located on the backplane PCB and configured to receive multiple insertable modules, respectively; an AC-DC power supply configured to generate an isolated DC output voltage; and multiple DC-DC switching regulator units corresponding to the multiple of slots, respectively, each DC-DC switching regulator unit separately receiving the isolated DC output voltage from the AC-DC power supply. Each DC-DC switching regulator unit includes at least one DC-DC switching regulator configured to convert the received isolated DC output voltage to at least one different DC voltage, respectively, available to the slot of the multiple slots corresponding to the DC-DC switching regulator unit. A switching frequency of the at least one DC-DC switching regulator in each DC-DC switching regulator unit is separately adjustable to provide the at least one different DC voltage.
