No Load Power: <0.05W; max input power: 3.5W
Output Voltage: 5V; max output voltage range: 4.9-5.3V or 4.8-5.2V; ripple wave 60mW
Output Current: 0-600mA; output indicator lamp 1mA red light
Output Power: 3W; efficiency 80%
Output Protection: overvoltage, overcurrent, overtemperature, overpower, short circuit protection etc
Applications: for zero line, live line intelligent switch, intelligent socket, equipment and instructions, other controllers etc.
Working temperature:-25~85℃

Installation Way:

Soldering the input and output port pin on the PCB as independent components.
Soldering the lead wire, and use the glue to fix.
PCB slotting, directly plug it on the PCB to solder

Note:

If it is used in single live line intelligent on-off value, take off the LED and change the starting resistor will be OK;
If you want to change 10M resistor into 20M, just remove the LED.

Product review & video

Hi, these 3 devices are buck converters and they make a great alternative to linear voltage regulators. In this video I'll show you in practice why and when you should consider using buck converters. Linear voltage regulators like this commonly used LM7805 are so cheap and so easy to use. Just supply those 2 pins with 7-16V, add a 10uF capacitor on the input, another one on the output and you get steady 5V. As we all know, nothing is perfect, and so are linear voltage regulators. They are quite inefficient, because they waste energy and produce a lot of heat. How much heat you may ask? Let's take an example. If you want to feed your voltage regulator with 9V and draw 500mA on the output, you will have to dissipate 2W of heat. The temperature of your LM7805 will definitely go above 100 degrees C or 212 degrees F. If you want to draw even more current, or increase the input voltage you mi
