## Long description

Volt Polska Power Sinus 4000 12V is an offline uninterruptible power supply (UPS) with a rated capacity of 4000 VA and a 12 V battery input. It provides temporary backup power and voltage stabilization to maintain continuity for connected equipment during mains interruptions and to reduce the risk of damage from surges and voltage fluctuations. The UPS delivers a clean sinusoidal output suitable for devices that require pure sine wave power and is intended for environments such as small server racks, network installations and telecom setups.
Advantages
This UPS offers automatic transfer to battery power on mains failure and an output that follows a sinusoidal waveform for stable supply to sensitive electronics. With a 4000 VA rating it supports moderate power loads, and the 12 V battery input allows compatibility with common lead-acid or compatible battery banks for extended runtime configurations. Compact offline topology reduces complexity while providing essential protection against short outages, surges and undervoltage conditions.
Suitable for
Small server racks and edge servers
Network switches, routers and access equipment
Telecom systems and VoIP gateways
Critical electronics requiring clean sine wave output
Key specifications
Topology: offline (standby) UPS providing automatic battery switchover
Rated apparent power: 4000 VA
Battery input voltage: 12 V
Output waveform: sinusoidal output suitable for sensitive loads

How to use
Install the UPS on a stable, ventilated surface near the equipment to be protected and the battery bank.
