AVANSA UPS 500W 12V Backup Power Supply for Circulation Pumps, Replacement Power Source for Boilers and Heating

Product detailed description

This backup power supply can be used to keep other electrical appliances running that require stable and consistent electrical power parameters. However, it should not be used as a converter (for unlimited operation from a 12V battery). The main feature of this device is the shape of the output power curve when running on battery. The curve is a pure sine wave, identical to the main power supply from your household grid. When the main power in your home is on, the backup power supply will charge the battery and ensure its long service life. The backup power supply (UPS) only works with an external 12V battery (24V battery for the 1050W model). Only a lead-acid type battery should be used, as the backup power supply is designed to charge this type of battery. The use of gel batteries is not recommended. WARNING! Before connecting the backup power supply, remove any metal objects (e.g. bracelets, chains, watches, rings, etc.). This is because a short circuit could occur, resulting in metal materials becoming hot on the user's body. When connecting the battery, observe the correct polarity: red (+ positive) - the cable is connected to the + terminal, and black (- negative) - the wire is connected to the - terminal. Metal connectors are used to attach the cable to the battery terminals. Before connecting, it is recommended to clean the battery contacts with a brush. Tighten the connector with a wrench to ensure a firm contact. Install the backup power supply (UPS) in a dry location, free of moisture, away from water or snow. The installation location of the backup power supply (UPS) must be large enough not to obstruct the unit's cooling system. The location should also be free of dust or coal dust, which could block the backup power supply's fan. The installation site should be well ventilated to prevent the system from overheating. To avoid electric shock, check that all cables are in good condition and have no 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 (230V, 50Hz) socket. Connect the device you want to keep running during a power outage to the back of the unit. Follow this order: connect the battery, connect the main power supply, 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 status and mains voltage. 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 the power parameters are outside the normal range, the backup power supply (UPS) will automatically switch to battery power. The switch to battery is shown on the display of the backup power supply (UPS). The device (UPS) also signals the switch to battery power with an audible alert. WARNING! This is only a safety device intended for use during power outages. When using this device, please do not leave it near fuel.
