Power Supply Crowbar

2005-11-22 by djbrow54

I am running a single HAA15-0.8-A power supply in my middle cabinet 
connected to two MOTM-960 distributions boards, one on each side.  I 
have been having problems with the power supply current limiting on 
power up.  My total load on this supply is 480 mA nearly balanced on 
both +/- 15 volts.

What have others done to deal with this?  I've moved some modules 
around trying to change the loading but it never really fixes it.

I've been thinking of adding a small sequencer to enable one of the 
960 distribution boards after a small delay.

Would some bulk inductance in series help?

Thanks in advance. - Dave
