Features: Support wireless control on the app with android/iOS available. You can connect the RD6012-W to app through Wi-Fi, remotely monitor and set the digital power supply on your phone. Support PC software control with Win 7/8/10 available. You can monitor and set the digital power supply via computer. Arrange more components in a limited space, 12A high current to meet your needs for high current power supply. 2.4 inch colorful LCD screen, view more information in one screen. Keypad and encoder potentiometer combination is convenient to adjust at big or small range. Use green charging terminals specially for the battery charging, you can use it to charge multiple types of batteries. Adopt high precision sampling chip, keep optimizing product hardware and software's algorithm, and ensure the accuracy and stability of measurement. You can set the value of over voltage protection (OVP) and over current protection (OCP), the output will be shut down autmatically when the output exceeds the protection value to prevent damage to the load. Not only displays data in digit but in curve, vividly show you real-time output voltage, current and power curve. Instantly store/call out the setting parameters and update the firmware for more convenient use. Note: *The feature of Wi-Fi is only for RD6012-W. *RD6012 only support PC software by connecting with USB micro cable. Do not support App. *For PC software, it only support win 7 or later for now. For APP, it only support android 5.0 or later. *S12A is suitable for RD6012/RD6012W and AC-DC 800W switch power supply. *If RD6012W can connect to the hotspot shared by the mobile phone but cannot connect to the router, you need to shut down the client isolation / AP isolation and WMM function.  *Please read the user manual carefully before use.
