Fonte de alimentação ininterrupta QOLTEC 53947 3 kVA 230 V 50 Hz

QOLTEC 53947 is an uninterruptible power supply (UPS) with 3 kVA capacity designed for 230 V, 50 Hz mains. It provides backup power and basic voltage regulation to protect connected equipment during mains interruptions and voltage fluctuations. Intended for environments where uninterrupted power is required to prevent data loss and allow orderly shutdowns, this UPS supports small servers, network devices, workstations and telecom equipment.

Advantages

The UPS delivers a continuous backup source with 3 kVA output capacity at nominal 230 V and 50 Hz frequency, offering short-term power support when mains fails. Built to maintain connected loads during outages, it also performs basic voltage regulation to reduce the impact of under- and over-voltage conditions. The unit is compact for its capacity and suitable for installation in small server rooms, office racks or next to critical equipment, allowing safe shutdown or continued operation for essential devices.

Suitable for

• Small servers and hybrid server setups
• Network switches, routers and other telecom equipment
• Workstations and professional desktop systems
• Storage devices and NAS units requiring orderly shutdown

Key specifications

• Output capacity: 3 kVA
• Nominal output voltage: 230 V
• Frequency: 50 Hz
• Function: backup power and voltage regulation
• Intended use: protection of IT, telecom and workstation equipment against mains interruptions

How to use

Install the UPS on a stable, level surface or in a compatible rack space close to the equipment to be protected. Connect the UPS to a properly grounded 230 V, 50 Hz mains supply and then plug critical devices into the UPS output sockets. Configure any available shutdown software or monitoring interface according to the manufacturer’s instructions to enable orderly shutdown of connected systems during extended outages. Periodically verify battery status and replace batteries according to the UPS maintenance guidelines to ensure reliable backup operation.

Recommendations

Place the UPS in a ventilated area away from direct heat sources and liquids. Do not overload the unit: ensure the total connected load stays within the 3 kVA output capacity. Regularly test the UPS transfer to battery and review battery runtime under typical loads to confirm it meets your shutdown or runtime requirements.
