Product information

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
  • Protection features: mains failure transfer, surge and undervoltage protection

How to use

Install the UPS on a stable, ventilated surface near the equipment to be protected and the battery bank. Connect the 12 V battery or battery pack to the designated input terminals following the manufacturer’s polarity guidance. Plug the protected equipment into the UPS output sockets and connect the UPS mains input to the AC supply. On mains loss the unit switches to battery power automatically; monitor the UPS status indicators to check battery charge and load conditions. Perform periodic battery inspections and replace batteries according to the battery manufacturer’s recommendations.

Usage recommendations

For reliable operation, match the UPS capacity to the combined power draw of connected equipment and size the battery bank to provide the required runtime. Use batteries recommended by the battery manufacturer and ensure proper ventilation. Regularly test the UPS transfer function and replace aging batteries to maintain backup availability.
