Each Amber Switch controls one appliance and is wired into the cable supplying the appliance. If several loads are available, and particularly on larger systems, more than one Amber Switch can be installed.
The Amber Switch requires no user intervention and will automatically switch the appliance on when the system frequency is higher and switch it off when the frequency is lower. The frequency setpoint can be adjusted during installation.
Amber Switch incorporates a number of features to ensure stable operation of an islanded power system:
Amber Switch can control loads up to 13A (3kW at 230V). Amber Switches should only be connected to non-essential loads (ones which can be switched off or on automatically without a problem).

Amber Switches are load control devices for small-to-medium islanded power systems, in particular those with ac-coupled renewable generation. They are suitable for a power system in which system frequency varies, depending on power availability and/or generator loading.
Amber Switch responds to a change in the system frequency. Each Amber Switch switches on when frequency is higher, and off when frequency is lower. No control wiring or signals are needed.
