Automatic switching between mains power and generator:
Detects mains failure and sends a start signal to the generator in about 2 seconds.
After starting, there is a pre-heating process. (~5 seconds), followed by the transfer of the load to the generator (indicator "GENERATOR").
When the grid returns and remains stable for about 10 seconds, the ATS reconnects to the public grid, waits 5 seconds in no-load mode, and automatically shuts down the generator ([turn0search12]).
Ternary start protection:
If the generator fails to start, it makes up to three automatic attempts (with intervals of 3s, then 5s). If rejected, the failure indicator ("FAILURE") lights up. The error is reset by pressing "Auto Transfer" ([turn0search12]).
Automatic battery charging:
Includes internal charger that provides constant current (~2A) until fully charged, then switches to float mode to ensure a charge is always available for starting ([turn0search12]).

Operating Voltage:
DC input: approximately 8-15V (frame power supply)
AC Charger: 90V to 250V, DC output 13.8V ±2% at 1A ([turn0search12])
Nominal supported currents (depends on the version, averages involve the 5-10kW of the Campeón models):
Single-phase (220V): 25A to 50A
Connections and assembly:
6-pole circular cable for connection to the generator control panel
Electrical/mechanical interlock between mains circuit and generator for safety
Use of contactors or motorized switches according to the rated current ([turn0search12],[turn0search6]).
LED indicators or display:
Lights for status: HOUSE NET (public network), GENERATOR (active generator), AUTO (automatic mode) and FAILURE (failure) ([turn0search12]).
Complete automation: with audiovisual detection of the grid status, automatic generator activation, and safe reconnection when mains power returns;
Greater reliability and safety: includes protection against start-up failures, overload, voltage changes, and process control;
Compact and protected design suitable for outdoor use or in technical environments, with an adequate degree of protection.
