Page "Dummy load" Paragraph 17

The equipment and power spectrum of such electronic loads begins with simplest circuits consisting in general of a potentiometer for current setting and a transistor circuit for power transforming.

Further developed electronic loads supply several operating modes, in most cases constant current, voltage, power and resistance.

Nowadays, the equipment may be controlled by a PLC or remotely by a PC.

Settings and measured values such as input voltage and actual load current are indicated on a display.
