It feels like a joke! I purchased the RD6012, and right after I placed the order, the RD6018 was released. Just last week, I bought the RD6012P, and now I come across this video!
sorry for what happened, for RD6012P, normally 800W PSU is already enough for RD6012 and RD6012P, for RD6018, if you use 220V AC input, 1200W PSU is enough, because for our RD6024, there is no PSU to let it full output, so that we design this 1500W PSU, after public testing it in China, we start to sell it
yes, when we designed the case, we already considered the models released next, so that this case can install all the PSU in our store(800W/1200W/1500W PSU)
I bought new RD-1500-68 PSU recently. It is buzzing like a spaceship. I don't mean fan noise, but electronic. I don't have oscilloscope to measure now, but I doubt output quality is good. Hear in recording here: th-cam.com/video/SDKGLBpQeuk/w-d-xo.html
hello, at the product page, about this high frequency noise, there is explaination, you can add a 5.1k ohm 3W resistor at the PSU output to reduce that, this noise comes when the device does not connect load to output
There is a high-frequency noise when the switching power supply is unloaded, Due to the large output power range of the product, in order to reduce the power consumption of the switching power supply when no-load, the PWM control chip will jump some control cycles. Assume that the original working frequency is 60KHZ. If there are more skipping cycles, the working frequency will be reduced to less than 20KHZ. This Sometimes a noise audible to human ears is produced. The size of this noise is also related to the production process of the transformer. Since the winding and paint impregnation of each transformer's coil are slightly different, the noise of each product's operation is slightly different.
@@rdtech9153 unfortunately this advice didn't help. I tried even 1k resistor without success. The sound changed slightly, but volume of the noise is still same. Very annoying and disturbing... I can't switch off the power supply so often between measurements and tasks. So it has to run for 2-4 hours and eg. 40% of it without load when setting up new task.
@@p0l0us hello, do you try when the output power is high, do you hear the noise? normally we use 5.1K ohm 3W resistor, it can help, but the noise will not disappear
Well done for starting to make your own power blocks! Keep it up!
thank you, yes, for now in our store, 800W 1200W 1500W PSU are produced by ourselves
Already found a 1500w power supply that works but good to know that you have this for sale now!
yes, for now we sell a batch of 1500W PSU. and now there is no stock, we need to wait the meterial to make the next batch

好东西👍
谢谢
Nice video. Does this 1500w PSU fit into the same body & head (Rd6018-W) meant for the 800w PSU?

Personally I would not buy this psu because it can't output 70 volts at 1500 watts with 110 volts ac input
hello, at 110V AC input, this PSU output is still 68V and you can adjust it to 70V DC, its max output power is 1200W, the voltage does not change
