#eevblog is #complaining about his #eps #emergency #power #supply not immediately switching #power #source https://youtube.com/watch?v=5JT8M8v_zNg What he actually wants is a #ups , an #uninterruptible #power #supply instead, which is what I #purchased recently. I use mine for #computers that cannot survive any amount of #power #outage . In theory he could run his #eps into a #ups , and then run the #fridge into that.
