This switched-mode power supply board can be used to supply the I2C modules or other devices with power.
All prices include Tax plus shipping costs
Delivery time 3-5 working days germany / about 10 days Europe.
Price changes and errors excepted.
The maximum input voltage range of the built-in switching regulator LM 2576 is 40V and delivers up to 3 A.
In the control cabinet you can thus generate further voltages from the most existing 24V DC.
Size of the circuit board 42 mm x 63 mm
