Model Inner boxDimension(cm) Outer boxDimension(cm) QTYProduct weight PS-305D 17*33*21 36*35*44 4PCS 4.6KG The advantages of our DC power supply 1.High precision and good technique to protect the product Safety and reliability. We are using advanced SAMSUNG IC according control software to shows. And in order to protect the product Safety and reliability, in software we make the Limit in the shows. (Some of factory products in order to save the cost are using Analog Circuitry to do,so their are precision Safety and reliability can not compete us.) 2.Good transformer Our transformer are using good conductor and high effcient magnetic core.So we no need make bigger ,but can satisfied the DC power suppy. (some of factory transformer material less efficient that can not load, so thier make bigger. that cause the weight heavy and high calorific value, so there are transformer can not compete us.)
