The ZK-4KX CNC power supply module they sent is not correctly working
By: Muhammad Naeem
I have bought a ZK-4KX CNC digial variable power supply module from them. Be aware that there are some serious faults and bugs in their power supply. I am listing a few below so that you know them before purchasing.
1. The current limitation feature is dangerously buggy; it sometimes reaches 3 times of the set current limit before adjusting itself which can easily burn or damage the powered circuits or devices using it.
2. If your load is pulling anything below 0.039A, it will show it as 0.000 Amp which is kind of deceiving when showing and claiming a current resolution of 0.001A.
3. You won’t be able to see the correct mAh consumption of the device you are powering with your power supply module if it pulls anything below 0.039A. It will keep showing just 00.000Ah and 00.000Wh no matter how much mAh, mWh the device has pulled.
When I contacted the seller, they said “we don't provide any functional answers or technical support”.
Being an engineer and a programmer, I am pretty sure that these faults are software related and I dont appreciate such reply from them. Please consider my review before buying anything from this store.
At least they delivered the power supply module so they are not a total scam.
They are not providing what they are claiming.
Only buy from them before doing complete research and ask them everything before buying.
