247.0. "DEC3000/500 POWER SUPPLY OUTPUT" by SCASS1::BROGDON () Mon Feb 03 1997 17:55

    Hello,
    
    
    	I have a customer that has a dec3000/500 they have added some
    3rd party disk & tape drives about 1 year ago and the system has run
    fine until recenty. The system began crashing 1-2 times a day with a ac 
    power failure. The power supply was swapped and would not come up until 
    1 of the disk drives was unplugged. My main question is how much +5v
    and + 12v power is available for internal disks,tapes and cdroms ?.
    
    The system currenty has no additional turbochannel modules and has 256
    meg of memory. the storage options are as follows
    
    type		+5v	+12v
    
    RZ26-E		1.2A	0.6A
    FUJITSU 2694ESA	1.1A    0.6A
    MIRCOP. 3243AV	0.9A  	2.8A
    RRD42		0.8A	0.25A
    WANGDAT 3400DX	2.0A	1.0A (OPERATING CURRENT)
    
    TOTAL CURRENT	6.0A	5.25A
    
    
    				Thanks, Robert Brogdon
    

    Hi;
    
    From the DEC Std 9 form for DEC 3000 M500....
    
    	+5 for CPU = 24 AMPS
    	+5 for TURBOchannel/Storage = 27 AMPS
    	+12 system = 8 AMPS
    
    Hope this helps
