This is a 100A single phase ATS (automatic transfer switch), which is a new, compact and cost-effective ATS unit made by Hyundai for those requiring instant power backup when there is a power cut for mains failure.

ATS units are wired directly into the distribution board and typically coupled to a diesel generator. When installed into your home or business premises, it will constantly monitor the incoming mains supply power. When the mains supply from the national grid fails, the ATS will automatically start the generator providing your home with backup power until the mains supply returns.

When the grid power comes back on, the ATS again will automatically stop the generator and return the household demand back over to mains. To view how this is achieved, we have set up a video which can be seen below.

The ATS connects to the generator using a length of communication wire (This isn't included in the sale of the ATS as the length will vary from one installation to another) which is shown in the video above. As the diesel generator will itself be kept in a standby mode, and only used infrequently, there may be considerable amounts of time during usage, which can normally lead to the battery draining down. The ATS has a built-in 12v battery charger which uses the communication cable to keep the generator battery charged up so that when you need it, the generator will fire up straight away.

An extremely easy model for any competent electrician to install, this ATS can be wired in without any issues, typically in only a few hours. A compact design the ATS unit itself meaures in at the following dimensions: H: 415mm x W: 440mm x D: 220mm, and is around 8kg in weight.

The ATS is compatible with a range of Hyundai generators, including the following units:
