dobry sprzęt
Great load for testing DC power supplies, either being batteries of dc/dc and ac/dc. You should know what you are doing using this product. Basic understanding of P=UxI is needed. Unit quality is good enough and functionality is great.
Easy to use. I use it as load for testing Bosch ebike batteries, 36v 3-4A, it's OK. An additional wt32-sc01 esp32-mcp2515 for the keep alive and display the status of the Bosch battery. Code: micropython.
Very good and accurate product. Using other versions for years.
Pretty good and a competitive price. Changing parameters is finicky since you need to keep the rotary knob pressed to switch among settings. I also don’t like that you get the splash screen on startup
