Best Affordable Electronic Load – Kunkin KP184 Review | Voltlog #299

Welcome to a new video, this will be a review of a new test instrument I discovered, you know I like electronic loads and I’ve tested a bunch of hobby grade electronic loads in the past, these were sub $50 items and that budget also meant they had some disadvantages like limited power, limited reliability, limited connectivity, limited functionality and limited accuracy. You were basically trading off a bunch of stuff to be able to get a cheap affordable electronic load.

This is the Kunkin KP184 and I believe this will be a game changer for those who are looking to get something a bit more professional but are still limited by budget and they can’t go for the better instruments starting at 500 USD. The unit is delivered in a large box with nice padding protection and inside you get the instrument, a user manual and a few accessories like some spade connector, an RS232 cable and some wiring.

Let’s talk a bit about the specs of this unit, I have the KP184 model which is like their better equipped model, it works with both 110 and 240VAC, the load voltage can be a DC voltage between 1 and 150V, up to 40A, up to 400W. Measurement accuracy is 0.05% + 5 counts for both current and voltage with 1mV and 1mA of resolution, we’ll be verifying that later. There is RS232 and RS485 connectivity with a modbus protocol which is specified in the user manual and there is a piece of software for the PC, you have to obtain it from the manufacturer which doesn’t respond to emails but I’ve managed to source it and I’m gonna put a link to this in the description below the video and I’ll try to connect it towards the end of this video.
