In Reply to: Yet another Zerozone PSU fuse issue. posted by Duster on July 20, 2017 at 15:25:43:
The 1.6a fuse on the 100VA is probably not underrated as per the math in my previous post. 50va/120V=.4166. .4166x 1.35=.562. The 1.35 is a "headroom" factor one reads about when looking into how to calculate a safe fuse value. They talk about going the closest next size up. Whoever is putting these things out either has their head up their you know what or my and Lew's calculation method is incorrect. I went through this with an electronics guy with my amp and this is the correct method for the ac primary fuse. My 5A peak current, 3A constant Tripp Lite came with a 5A fuse if I remember correctly,which seems incorrect also for a primary fuse. Maybe it's a secondary fuse but that would mean the Tripp Lite had no primary fuse. If it's a primary fuse that would mean it was a 360 watt to 600watt peak wattage device. No way Jose. While my calculations my be missing something,something sure is wrong with what you PS people are doing. Safety first, I always say. T456
