For example, if the max current of your load device is 10A, then choose 10A\/0.8=12.5A at least for resistive loads according to international standard.  If the load device is motor or compressor, then you may choose 10A\/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current. \u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":48369484169442,"sku":"P353532473197598272","price":16.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/8737\/6098\/files\/542180b99641c3da9375ae386f930fe81f98610660b53cd732ce3479d6eed1da.jpg?v=1788842974","url":"https:\/\/mopdolphin.shop\/products\/cllena-dc-48v-step-down-to-24v-30a-720w-voltage-reducer-converter-waterproof-dc-dc-buck-transformer-power-supply-pack-of-2","provider":"My Store","version":"1.0","type":"link"}
