Add to Cart:
Input voltage: 4.5-60 V
Output voltage:3-35 V
Rated current:2A;maximum current:3A(with heat sink added),if the output power is more than 15w,you’d better add heat sink.
Conversion efficiency:less than 92% (the larger the voltage is,the more efficient the conversion is)
Static power comsumption:about 6 mA only
The smallest voltage difference:1.5V (in order to keep stable output)
Work temperature: -40 to +85 degrees centigrade
Load regulate rate:±1%
Voltage regulate rate:
Dynamic response rate: 5% 200us
Short-circuite protection:by limiting,recover automaticaly
Output ripple:15mV(max) when input 12V and output 5V /3A,40mV(max) when input 24V and output 12V/3A
Input reverse protection:none,you can add over-current protection device in serial-connection
How to use
First give the right input voltage,and then monitor the output voltage with a multimeter and regulate the potentiometer to change the output voltage until you get the right output.The output voltage can be regulated continously.
Because it is a buck module, so the output voltage is at least 1.5V lower than the input.
- power supply in your cars: just connect the module input to the car power cigarette holder, you can adjust the potentiometer to power different devices,such as your mobile phone,mp3 and so on.
- power supply for other elec modules:when you are working in a elec project,and you need different voltages,it will be a good choice to use this module.
