Control Devices and Monitors

Stunning controllers are becoming increasingly sophisticated as more research into the effect of electrical currents on animals is carried out. They range from simple transformers, which deliver a fixed voltage output, to complex electrical systems, which control the voltage, frequency, waveform, and duration of application.

monitorsSome systems provide current monitoring, which enables the current profile from each stunning operation to be logged and reviewed. Sensor switches are incorporated into some models to prevent the flow of current if the resistance of an animal’s head is above a set level. All electrical stunning equipment must feature meters, which display the current and voltage, and audible and visible signals to warn the operator if the stun duration falls below the required level. These displays can be separate to the control unit, but must be visible to the operator.
