Standby power for heating systems is designed to supply electricity to electricity consumers for several hours in the event of a mains power failure. It is most commonly used in heating systems where water pumps need to operate even in the event of a mains power failure. In addition to heating systems, the uninterruptible power supply can also be used to power solar systems, security systems, alarm systems, video systems, computers, servers, check-in systems, automatic garage doors, etc.
The essential advantage of the back-up power supply for heating plants is that they have a pure sine wave rectifier built in, and the battery is installed next to the appliance. The capacity of the battery is determined by the desired operating time of the back-up power supply. Conventional UPS devices in this price range can only provide a short operating time as they have insufficient charging current and insufficient space to accommodate larger batteries.
A UPS for heating plants consists of a rectifier with a true sine wave rectifier, a battery charger and electronics to ensure that the battery is switched on in the event of a power failure. The device shall have one shunt output for powering consumers at the rear of the device.
A pure sine wave rectifier ensures smooth operation of the pumps and electronics of the heating system. The battery charger has a maximum charging current of up to 15A. The charging current is automatically adjusted to the battery capacity. The capacity of the battery depends on the power of the consumer and the charging time. The battery is easily connected to the back of the UPS unit. The charger for heating plants should charge a conventional VRLA battery with a capacity of 100Ah in about 8 hours.
Typically, uninterruptible power supply systems have a built-in LCD display on which the operation of the system can be monitored, as well as the state of charge of the battery.
For the correct operation of the system - charge and discharge mode - we use only dry acid-free batteries with so-called VRLA/AGM technology.
