For APP, it only support android 5.0 and above.For APP and PC software, because there may be incompatibilities problems, please download first before buying , if you can download and install, you can make order, or else stop buying. If you don"t test the PC software and APP function before buying and find that the products works fine except the PC software or APP, we refuse to refund.
3. If you connect inductive load (such as motor), the max working current is 1/3 of range. don"t exceed it.
4. When get the PSU, please use multimeter to check if the real output voltage is stable and fits the rated voltage, to see if it is damaged on the way, if the output is abnormal, please contact us, do not connect it to RD power supply to avoid more loss
5. There may be scratches on the surface but it doesn"t affect the product performance, please do not be over picky, and if you do mind this, please do not buy this product
6. You can only connect the cables with a foundation in electronic and electrical engineering and it must be reliably grounded!
7. Due to express delivery, some power supply warranty labels may be damaged, which does not affect product warranty!
8. Due to the different power supply production batches, the internal material details may be different, hereby explain!
9. There is a BACKUP fuse in the RD6024W box, if you burn the fuse, you can insert the fuse in the socket next to the burned one for temporary use and it supports only 10A, so it is better to remove the damaged fuse and solder the good fuse on the same position for full output.
10. When intall our switching power supply into our case, please follow our instruction to assemble, do not remove the shell of the PSU to use. After the shell of the switching power supply is removed, the structural change of the heat dissipation system will lead to insufficient heat dissipation, and some components will be overheated and damaged, in this case we don"t offer after sell service
