Models are available with either four or eight outputs at a range of voltages. All of them have either fuse protection or PTC circuit breaker protection, and are compatible with a variety of power supply sizes. The four output models have an on/off power switch, and the eight output models have a main power indicator to show AC, DC or reverse DC input.
