| Electronic load, why only constants? |

| FriedMule:
I am searching for gear to bye and am wondering on why electronic loads only have constants like constant voltage, current and so on. Do none ever need to know how something react on suddenly change in current, i.e. a relay turning on a fan or a heater? Or what about voltage change? |
| Pinkus:
most do have a RS232 (often TTL) or an USB interface where you can program them to do what you want (e.g. jump from 10ma to 10A and back for 1000 times. |

Check this document: https://bkpmedia.s3.amazonaws.com/downloads/manuals/en-us/8600_Series_manual.pdf Pages 51-55 seem to answer your question. |
| FriedMule:
Okay thanks, great news (for me) :-) I hope to spend less then 500$, do you have some recommendations for a decent lab? |

BK Precision has an entry model for $545. http://www.bkprecision.com/products/dc-electronic-loads/8540-150-w-dc-electronic-load.html I recommend you check its specs and manual to see if that is what you need. By the way, the term "constant" is a bit misleading. This doesn't mean that things cannot vary. It only means that this is the parameter that you're going to control, regardless of the others. So, in constant current (CC) mode, your dummy load will maintain the programmed current no matter how the other parameters (voltage, resistance) react. The same is true for CV or CR. Some models even offer CP (constant power). |
