Electronic load

Electronic load
For testing a power supply, a fairly large resistive load, preferably variable, is needed. Moreover, testing of the dynamic performance of the supply makes it essential that this load can be switched on and off rapidly. The load described in this article has been kept relatively simple, yet it can dissipate 130 W for brief periods and may be switched on and off at a repetition rate that can be set between 10Hz and 100 kHz.
