I bought the 433 MHz module, and received in good time. It works absolutely fine with Sinilink XY-SK150X DC Adjustable Power Supply 6-36V 0-7A 150W which I purchased before this module. _Great idea to interface this receiver with Power supply module. The module connects with the MODBUS 4 pin interface behind the power supply module (circle red in image 4). The Power module is Easily controllable now, including power on, off, V set, I Set. I am glad I bought it. _There is no need to point remote directly towards the module, it senses even u do not, that's the advantage of 433MHz transmission. _There are other versions available for this remote module like 2.4 GHz Wifi and Bluetooth, etc, but to my needs this suited the best hence bought it. _Highly recommended product. and seller.
I haven't tried this yet.
