FB8189 FASTBUS POWER SUPPLY
This unit is a rack mounted Power Supply Assembly intended for use with a FASTBUS crate. The FB8189 provides the +/- 15VDC, mains switches and metering, and the wired frame for mounting the switching regulators which supply the +5V, - 5.2V, and -2V DC digital power to the crate. All outputs are monitored by dual (voltage & current) LCD digital voltmeters switch selected from the front panel. Input voltage and current are also metered at the front panel. The FB8189 also provides the switched mains voltage for a blower and external switching regulator power supplies. Any combination of three standard 5"x 8"x11-14" packages can be added by inserting them into the slots provided at the rear of the unit. Current options available are 120 or 200A for -2V and 200 or 300A for the -5.2 and +5. For units with switching regulators providing 200A or less each, inputs of 100-130 or 200-260V AC 47-63Hz are available. For crates requiring any switching regulator with an output above 200A units are available only with 200-260VAC 47-63Hz input. All switching regulators have self-contained fans which circulate air inside the chassis. All units have an ambient air temperature operating range of 0-50 degrees C. Switching Regulator Power Supplies plug into pre-wired slots at rear of Power Supply Chassis. The -5.2 and +5V regulators are interchangeable. The +15V DC regulators, mains switching, and metering circuitry are pre-wired with plugs, switching current shunts, and all wiring including power leads to the crate.
