Heating systems, including pump circulators and pellet, gas or oil burners, are connected to the 230V mains, but power cuts can cause overheating or even damage. Therefore, the systems must be protected by an adequate back-up power supply.
An essential advantage of the back-up power supply for circulators in our range is that it has a pure sine wave rectifier and a battery that is located outside the unit.
Cheap modified sine diverters, which are usually used with computers, eventually break down the motors on the pumps, which is also immediately audible with loud pump operation. We have therefore chosen a backup power supply with a pure sine wave rectifier, which provides electricity of the same characteristics as the mains electricity.
The capacity of the battery shall be determined by the required run time in the event of a power failure and the consumption of the connected devices.
We advise you to purchase a cyclic lead acid battery (VRLA), not a car battery, to ensure that the battery lasts longer and can be discharged repeatedly.
