Features: 1. Super material: It is made of electronic accessories, nickel plating on surfaces(anti-oxidatioan), inner conductor: pure copper.it is long lasting and durable for you to use. 2. Synchronous rectification technology: Synchronous rectification uses a dedicated power MOSFET with very low on-resistance to replace rectifier diode to reduce rectification losses. 3. Wide Use: It can greatly improve efficiency of DC / DC converters. synchronous rectification technology is to greatly reduce rectification loss at output end of switching power supply, thereby improving conversion efficiency and reducing heating of power supply itself. Description: Widely uses in power transformer, DIY adjustable power supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fan, battery conversions, micro-controllers, and electronic projects. so on. Maintain stable output voltage and limit output current over a range of input voltages. Specifications: Material: metal Color: silver & blue Size: 60mm*53mm*22mm Input: DC5-30V, 8AMAX Package Included: 1 x Adjustable Power Module Notes: 1.
