Mains blackout is not dangerous for gas heating systems. There exists an explosion hazard for hotwater chimney places and boilers using solid fuel with closed circuit and a circulating pump. 

There can be used ENiXUS power supply to solve the problem. According to need, it is possible to use a power supply with sinusoidal output or output with modified sine - trapezial. The choice depends on the type of the powered device.

Characteristics:

• nominal input range 230V/50Hz (90 V – 264V)
• surge protection on input - it will protect your device during overvoltage of the input mains
• during failure of the power supply, the output remains powered from the mains
• very low power consumption in mains mode – minimal operating costs
• manual start/stop of backup from the battery by two control buttons
• possibility to connecto an external thermostat – for switching of the boiler for the purpose of tempering
• version with the internal 12V battery with a capacity 12 / 24 Ah or version for connection of the external battery
• protection against a reverse polarity of the battery
• sufficient power of the charger for charging of an external 12 V battery with a high capacity (up to 150Ah – depends on version)
• version without an internal battery can be used as a charger – charging of car battery
• dry contacts indicating the basic conditions of system
• SMS notification about the operation of the device and also its control - (optional)
• simple installation
