This module has advanced quality...
This product is an AC DC voltage source that feeds to the 230V AC supply network and provides a fixed and stable 12V DC output voltage supplying a maximum current of 30A. Also, the maximum power output from the source is 360W.
This module has the advantage of being remote controlled and having four relays that work on a voltage of 12 V with a very small current draw of 5mA.
KXN-3030D Power Supply with Digital Display (0 - 30 V, 30 A)
RXN-305D Laboratory Source with Digital Display (0 - 30 V, 5 A)
LM2596 Step Down DC-DC Power Supply Module with LED
This product is a switching voltage source and can provide a constant voltage or constant current output. With this mode of operation, it has very good efficiency and dissipates only very little heat compared to a linear source. The functions of the three potentiometers can be seen in the presentation images.
RXN-1503D Laboratory Source with Digital Display (0 - 15 V, 3 A)
5 A Power Supply with Adjustable Current and Voltage
This module allows you to control high voltage devices, like the home appliances, using a 5V signal. The relay module is capable to work with voltages up to 250 VAC and supports currents up to 10 A, making it ideal for home automation.
This motor driver shield is based on L293D motor driver chip which is designed to provide bidirectional drive currents of up to 1.2 A each bridge with thermal shutdown protection at voltages from 4.5 V to 36V.
