Uninterruptible Power Supply (UPS) QOLTEC 2000VA / 1200W Line Interactive with LCD, USB and RJ45

The QOLTEC Uninterruptible Power Supply (UPS) 2000VA / 1200W Line Interactive provides battery backup and surge protection for home and small office equipment. The unit maintains power continuity during outages, conditions incoming voltage with automatic voltage regulation, and presents operating status and settings on an integrated LCD. Communication via USB enables monitoring and controlled shutdown, while RJ45 protection helps safeguard connected network lines. Designed for everyday protection of PCs, network devices, NAS units and small servers, this UPS balances runtime and power capacity for orderly shutdown and data protection.

Advantages

This line-interactive UPS offers 2000VA / 1200W rated output to support multiple devices during short power interruptions and provide sufficient reserve for controlled shutdown of sensitive equipment. The built-in LCD delivers clear, real-time information about input/output voltage, battery status, load level and operational modes, simplifying system management. USB communication supports integration with monitoring software for automated shutdown and alerts. RJ45 surge protection extends hardware protection to Ethernet lines, reducing the risk of network-related damage during electrical events.

Suitable for

• Desktop PCs and workstations requiring safe shutdown
• Small home or office networks and routers
• Network-attached storage (NAS) devices and external drives
• Small servers and critical peripherals
• Point-of-sale and business terminals

Key specifications

• Output capacity: 2000 VA / 1200 W (line-interactive topology)
• Display: integrated LCD for status, settings and alerts
• Communication: USB port for monitoring and shutdown control
• Network protection: RJ45 surge protection for Ethernet lines
• Voltage regulation: automatic voltage regulation (AVR) to correct minor sags and surges
• Output waveform: simulated/stepped sine wave (typical for line-interactive models)
• Typical applications: desktop systems, small servers, NAS and network devices

How to use

Install the UPS on a stable, ventilated surface near the devices to be protected and connect equipment to the battery-backed outlets. Connect the UPS to a grounded mains outlet and power it on. Use the LCD to review input voltage, battery charge and load status. For monitoring and automated shutdown, install compatible UPS management software on connected systems and link the UPS via the USB port. Protect network equipment by routing Ethernet lines through the RJ45-protected ports where applicable.

Usage recommendations

For reliable operation, periodically test the UPS under load to confirm battery performance and run scheduled self-tests if supported by management software. Replace batteries according to the manufacturer’s interval or when runtime becomes insufficient for an orderly shutdown. Place the UPS away from heat sources and ensure adequate ventilation; avoid placing heavy objects on the unit. When protecting network devices, ensure Ethernet cabling uses the protected ports to benefit from RJ45 surge protection.
