set2: 5 x DC-DC Voltage Regulator Module + 1 x car boat Rocker SwitchLight source: led rated at 12V DC 16 should be a hole 2 cm / 20mm. These low 12V switches of Fund are very useful for the projects, the switch has three terminals 4.8 mm (Pos, Acc, Neg). When the switch is lit.High Quality: with work indicator, standard contact gold-plated socket. Pure copper conductor, nickel-plated surface, anti-oxidation, more durable.Input voltage range: 6-24V (9V/12V/24V); Output voltage: 5.2v (Considering charging line loss, the output end is about 5.2v and the load end is about 5V); Output current: 3A (Steady output current is 2A without cooling device). Note: positive and negative can not be reversed, and the input voltage can not exceed 24V, otherwise it will lead to chip damage!Wide range of applications: can be applied to mobile phone charging, car charging retrofit, driving recorder power supply, household power supply, intelligent plugging transformation, fast charging adapter, etc.Operating Temperature: -40 Celsius - 85 CelsiusEasy setupWhen the switch is lit.Quiescent Current: 25uAConversion Efficiency: up to 98%(MAX)(I=7V,O=5V)Switching Frequency: 435KHzDisplay: with load LED indicatorInput Mode: IN+ input positive, IN- input negativeOutput Port: USB(dual port)Applications: Compatible with many phone models. This module can be applied to mobile phone charging. Car charging retrofit, driving recorder power supply, household power supply, intelligent plugging transformation, fast charging adapter, etc.Note:When working in power, you can not contact the circuit board on the sampling resistor, IC pin, otherwise it may lead to damage to the output voltage of the device!For some of the poor electronic base customers- Do not think the nominal 3A current will burn the phone burn equipment!Charging current is determined by the phone or equipment! Most mobile phone charging current is 0.8-1.5A.Colour: green/blueMaterial: PCB/MetalDC-DC Voltage Regulator Module Size: 28.5mm x 14mmPackage Contents:5 x DC-DC Voltage Regulator Module1 x car boat Rocker SwitchOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
