-- [ From: Paul Herrick * EMC.Ver #2.3 ] -- Does anyone know of any regulatory reason to control the startup surge current to ITE units? We have measured this startup current to be up to 90A for the first half cycle of applied voltage. The unit is cord set connected and uses four switching power

While you appear to be looking at non-military applications, the U.S. MIL-STD-1399/300A paragraph 5.2.9 limits the surge current per its Figures 14 and 15. Jim Sketoe >>> Paul Herrick <0007515...@mcimail.com> 04/22/97 09:09pm >>> -- [ From: Paul Herrick * EMC.Ver #2.3 ] -- Does anyone know of a

The safety agencies will primarily look to see if the inrush will cause nuisance tripping of any overcurrent protection devices, including the branch circuit protection, and sometimes effects on additional earth leakage current. For your application, the North American agencies will assume branch
