2221.0. "DH900MS Power Source Requirements" by ANGLIN::CLAYTON (Merlin Clayton (314)947-6763) Wed Apr 26 1995 18:32

Do not have the environmental specs available for the DH900MS backplane and 
respective power supplies.

I need to know what the power source requirements are for a DEChub 900 MS
with three power supplies. i.e., how many amps do 3 power supplies pull at 
120V?

I need this to estimate how much power we need for a trade show we are doing
locally.

Any help would be appreciated.

Thanks.

2221.1AC input specs from DEChub 900 Multiswitch manual...NETCAD::BATTERSBYWed Apr 26 1995 19:0612
    The DEChub 900 Multiswitch owners manual specs out the AC input
    as follows. These numbers probably assume the three pwr supplies.
    (extracted from page A-4)
    
    Table A-8 Electrical Specs
    ----------------------------
    input voltage   - 88 to 264 volts auto-ranging
    line freq       - 50 to 60 hz
    input current   - less than 10 amps
    max heat diss   - 730w 
    max input power - 1000VA
    consumption
2221.24.125 Amps?ROMEOS::HARRIS_MASales Executive IIMon May 22 1995 21:466
    Another way to guage is is EACH power supply delivers 165 Watts. 3
    power supplies yields 495 watts. 495 watts at 120volts = 4.125Amps.
    
    (Or there-abouts...)
