Laboratory power supply Zhaoxin RXN-305D 30V 5A


Average grade


Customers opinion
It works and that's enough for me...
So far it works, it is easy to use, one downside is that there are no instructions in Polish.
Perfect in the school lab
everything's fine
Super power supply for this price :)
Exactly what I wanted. Small, light, accurate enough.
A very good power supply. I recommend.
Solidly built - the weight alone shows it. If someone has not used such equipment so far, I recommend caution when setting parameters - it is worth training.
The equipment is very necessary, I use it for all the repaired devices, it more than meets my expectations.
The best price / quality ratio, intuitive operation, multimeter measurements are consistent with the display indications. One disadvantage - no connection cables (I think they were in the previous iteration).
All is great
Great power supply! Unfortunately, the set did not include universal cables for it (those to be connected to the front), only a power cable (network).
Nice power supply for the price. It is a pity that there are no wires with a banana plug in the set
everything's fine
