Feature: 1. EASY AND DURABLE: Buck transformer is easy for you to install, possess high performance and high conversion rate up to 96%, provide great convenience for your life 2. EXCELLENT PERFORMANCE: Buck transformer adopt excellent components, synchronous voltage regulation technology, very low heat, sufficient power, stable state 3. LOW HEATING: DC to DC buck converter adopt multiple ultra low impedance ripple electrolytic capacitors, iron silica aluminum magnetic ring multi wire wound inductors, possess low heat generation, large pass through current 4. WATERPROOF HOUSING: Buck transformer use a fully sealed housing as a heat sink, IP67 waterproof, shockproof, dustproof, which is more durable 5. MULTIPLE PROTECTION FUNCTIONS: Buck converter built in overvoltage, undervoltage, overload, overheating and short circuit protection, very reliable 6. WIDE APPLICATION: Voltage reducer is widely used in vehicles, safety systems, hospital equipment, telecommunications, electrical equipment, LED light strips, motors, security equipment, etc. Specification: Item Type: Buck Transformer Output Current: 10A Conversion Efficiency: 96% Output Power: 120W Operating Temperature: -20℃~80℃ Waterproof Rating: IP67 Size(LxWxH): Approx. 74 x 74 x 30mm / 2.91 x 2.91 x 1.18in. Package List: 1 x Buck Transformer Note: 1. In order to ensure the normal operation of the converter, the input voltage must not be lower than the minimum or maximum input value limited by the product, the input voltage value must be higher than the output voltage value of 2V, if there is no 2V pressure difference, the output value will be lower, but will not damage (affect) the use of the converter.2. The input current must be greater than or equal to the power required by the output load device(such as: the power of the load device need 100W, then the input power must be greater than or equal to 100W). In the use of the converter, the current of the load device can not be greater than the maximum current value that the converter can withstand, and leave a margin for the converter as much as possible to ensure that the converter work normally to achieve the highest conversion efficiency.3. The positive and negative poles of the converter cannot be reversed when in use, which may cause damage to the converter. It is recommended to add a suitable safety tube at the input end when in use.4. The chip work in light load mode when there is no load, and the output voltage may vary within a certain range.
