Dummy load

A dummy load must be chosen or designed to tolerate the amount of power that can be delivered by the transmitter.

[3] Typically it consists of a resistor attached to some type of heat sink to dissipate the power from the transmitter.

The ideal dummy load provides a standing wave ratio (SWR) of 1:1 at the given impedance.

There are many designs for loudspeaker simulators, which emphasize different characteristics of the actual speaker, such as the voice coil's inductance, mechanical suspension compliance, and cone mass.

Electronic loads are used in diverse applications, particularly for the test of power supplies, batteries, solar and fuel cells, generators.

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

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