Certificates: CE\/RoHS, 1 year warranty, lifetime up to 100,000 hours.  Package included:  1 x DC 48-12V 50A Voltage Converter Questions: How to choose the correct current for loads?  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":44804947443754,"sku":"P353533338948083594","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/9912\/3498\/files\/58f00ebc83648a2ca06f79a8536124c8fa4e851907477f82481760283c2a8b61_d26b152d-d10f-4458-a012-b601b103f4a5.jpg?v=1788746222","url":"https:\/\/awdasfasg.shop\/products\/cllena-dc-36v-48v-step-down-to-12v-50a-600w-voltage-reducer-converter-waterproof-dc-dc-buck-transformer-power-supply","provider":"My Store","version":"1.0","type":"link"}
