• 12V DC Voltage Transformer：Input range:20V to 40V; output voltage : 12V(fixed output) output current : 40A output power : 480W (MAX). Be sure to insulate the wire 0.4 inches (10 mm or so) and insert it into the plug when installing.
• Heat Dissipation Performance：The 12V voltage regulator has IP67 waterproof classification, compact aluminum housing, epoxy resin potting, 100% waterproof, dustproof, shockproof, better heat dissipation performance.
• Intelligent Protection：Assembled with smart chip, equipped with intelligent overcurrent/overload/low load/short circuit/overheat protection by using the 12 V power transfomer voltage.
• Widely Application：The 12 V DC voltage converter is widely used in the fields of automotive, photovoltaics, industrial plants, motor vehicles, boats, agricultural machinery, camping, mobile structures, hobby and DIY etc.
• Please Note：The load connected to the transformer converter output should not exceed the specified maximum load. (Any greater load will damage the buck converter).The 12 V DC power converter adapter does NOT have input reverse protection, pay attention to the input correct, negative reverse, will lead to permanent damage to the product.
