DIY Constant Current Electronic Load

Описание

Design originally based on Dave Jones's Circuit and mjlorton videos.

A really useful and simple Do-It-Yourself Constant Current Electronic Load.

Components used:
1x N Channel MOSFET (preferably logic level MOSFET)
2x 10k Trimpots
1x Dual operational amplifier (op-amp) you can use single or quad op-amp even better a rail to rail op-map.
1 Ohm 100w resistor as current sense.
Some heatsinks, cables and bits and pieces.
1uf Cap and 10K resistor(revision)

Note:
One trim-pot will be replaced by 10 turn 50K potentiometer as mine haven't arrived yet for more precise current tuning, and there will be further tweak to stabilize current at lower voltage and few resistors to avoid oscillation due to gate capacitance.
