Backup Power Supply for Circulation Pumps AVANSA UPS 300W 12V + 45Ah Battery, Pure Sine Wave, for Boilers

Product detailed description

This backup power supply can be used to ensure the operation of other electrical appliances that require stable and consistent electrical power parameters. This product should not be used as a converter (with unlimited operation from a 12 V battery). The main feature of this device is the shape of the output power curve during battery operation. The curve is a pure sine wave, identical to the main power supply from your home's electrical grid. When the main power from your home is on, the backup power supply will charge the battery and ensure a long battery service life. The backup power supply (UPS) works only with an external 12V battery (for the 1050 W model, a 24V battery). Only a lead-acid type battery should be used, as the backup power supply is designed for charging this type of battery. The use of gel batteries is not recommended. WARNING! When connecting the backup power supply, remove metal objects (e.g. bracelets, chains, watches, rings... etc.). This is because a short circuit of electric current could occur, causing metal materials to spatter onto the user's body. When connecting the battery, observe the correct polarity: the red (+positive) cable must be connected to the + terminal and the black (-negative) cable must be connected to the - terminal. Metal connectors are used to connect the cable to the battery poles. Before connecting, it is recommended to clean the battery contacts with a brush. Tighten the connector using a wrench to ensure a firm contact. Install the backup power supply (UPS) in a dry place, free of moisture, out of reach of water or snow. The installation location of the backup power supply (UPS) must be large enough not to obstruct its cooling system. Furthermore, this location should be free of dust or coal dust, which could block the fan of the backup power supply. The installation location should be well ventilated to prevent the system from overheating. To prevent electric shock, check that all cables are in good condition and free of exposed, uninsulated sections. Operation of the backup power supply (UPS) may cause sparking. The backup power supply should not be installed in flammable environments. WARNING! The backup power supply (UPS) only works when connected to an external battery. It should not be used without a battery connected. After connecting the battery, plug the main power cable into a grounded socket (230V, 50 Hz). On the back of the unit, connect the device you want to keep running in the event of a power outage. Follow this order: connect the battery, connect the mains power, and then connect the consumer (device) to the backup power supply (UPS). To turn the unit on, press and hold the power button (ON/OFF) for 4 seconds. System operation begins with automatic detection of the battery and mains voltage status. If the battery voltage drops below 10.8V, the battery may be damaged and cannot be started. In the event of a power outage, or if its parameters are not within the normal range, the backup power supply (UPS) automatically switches to battery operation. Switching of the backup power supply to battery operation is shown on the display of the backup power supply (UPS). The device (UPS) also signals the switch to battery operation with an audible signal. When the battery voltage drops below the minimum value (the battery is discharged), the backup power supply (UPS) increases the frequency of the warning sound and disconnects the power supply. If a device connected to the backup power supply (UPS) exceeds the maximum power by 110%, the backup power supply (UPS) will start emitting an intermittent acoustic signal and switch off automatically. For inductive devices (e.g. water pumps and electric motors), it is recommended to use the device up to 50% of the maximum power of the backup power supply (UPS), as inductive devices may require double the power value at start-up. WARNING! Danger! Do not touch the battery terminals during operation. To stop the backup power supply (UPS), hold the ON/OFF button for 4 seconds. The backup power supply will then emit an audible signal and stop. To extend battery life, it is recommended to carry out a full discharge and full charge cycle of the battery at least once every 2 months. Perform this operation even if there were no power outages within the 2-month period and the battery remained fully charged the whole time. WARNING! This is only a safety device used only in the event of a power outage. When using this device, please do not leave it near fuel. This set includes a 45Ah battery. Technical data: maximum capacity: 500 VA maximum rated power: 300W main input power: 150 – 270 VAC input frequency: 45 – 65 Hz output power: 207 – 241 VAC input frequency: 50 – 60 Hz switching time: <4ms battery capacity: 12V DC overload protection: 110% 130% (30 seconds) standby consumption: 22W dimensions (H/W/D): 18.5x14.5x34 cm the backup power supply is suitable for appliances with a combined maximum output of approx. 250 W The backup power supply does not include a battery! It belongs to the group of professional automatic backup power supplies (UPS) specially designed and manufactured for the continuous power supply of solid fuel boilers in the event of a main power failure. In the event of a power failure, the backup power supply (UPS) provides immediate power from the battery, so that the circulation pumps keep running and the boiler cools down safely. Main functions: The backup power supply (UPS) stops in the event of a discharged battery. If the battery is discharged to 10.8V, the backup power supply disconnects the power supply to prevent damage to the battery. Overload protection: If the load on the backup power supply (UPS) exceeds 110% of the rated power, the backup power supply (UPS) will stop to prevent damage. Short-circuit protection: The backup power supply (UPS) stops in the event of a short circuit. – Voltage regulator (AVR) ensures a constant voltage for devices within the given range. Battery activation: the system switches to the battery and provides continuous power to the device. Automation: if the mains power supply is abnormal, the backup power supply automatically switches to the battery. – Conversion for starting a task: in some cases, a higher starting power than the rated power of the backup power supply (UPS) is required. In this case, the backup power supply (UPS) solves this problem by supplying 110% of its capacity. After delivering this capacity, it switches off. High charging current: the initial charging current is about 10A. It charges the battery in a shorter time than standard chargers. Maintaining the battery in standby mode: after the battery is fully charged, the backup power supply (UPS) keeps the battery charged. To achieve optimal results, the battery must have a capacity within the range of 40 Ah -150 Ah. Do not use a battery with a capacity lower than 40Ah, as the initial charging current of the backup power supply (UPS) (up to 10A) could reduce its service life. For a consumption of 100W: a backup power supply (UPS) with a 65 Ah battery will run for 3.5 hours a backup power supply (UPS) with a 120 Ah battery will run for 6.5 hours a backup power supply (UPS) with a 150 Ah battery will run for 8 hours For a consumption of 200W: a backup power supply (UPS) with a 65 Ah battery will run for 2 hours a backup power supply (UPS) with a 120 Ah battery will run for 3 hours a backup power supply (UPS) with a 150 Ah battery will run for 4 hours For a consumption of 300W: a backup power supply (UPS) with a 65 Ah battery will run for 1.5 hours a backup power supply (UPS) with a 120 Ah battery will run for 2.5 hours a backup power supply (UPS) with a 150 Ah battery will run for 3 hours
