UPS RACK 19" 3000VA/2400W RTS-LI-3K0-3U-LCD-4x9

The RTS-LI-3K0-3U-LCD-4x9 is a high-performance Line-Interactive UPS with a power rating of 3000 VA / 2400 W, designed to protect servers, networking equipment, telecommunications systems, and industrial automation devices. Thanks to its pure sine wave output, advanced AVR voltage regulation, and 19" RACK 3U design, the unit provides a reliable power source for demanding IT and telecommunications installations.

The TS-LI series utilizes Line-Interactive technology (VI-SS-111), providing a pure sine wave output voltage in all operating modes:

• Mains mode – pure sine wave
• Battery mode – pure sine wave
• AVR voltage regulation mode – pure sine wave

This allows the UPS to safely operate with servers, active network equipment, telecommunications exchanges, surveillance systems, and devices equipped with active PFC power supplies.

Key Design Parameters:

• Height: 3U

• Dimensions: 440 × 410 × 132 mm

• Net weight: 26.7 kg

• LCD display showing operating parameters

• Intelligent DSP control

• Adjustable cooling fan speed

The unit is designed for installation in standard 19" rack cabinets. Its robust enclosure also allows standalone operation.

The UPS is equipped with four internal AGM VRLA batteries rated at 12 V / 9 Ah each, operating at 48 V DC. This battery system ensures effective backup power during mains failures.

Typical Backup Times:

• 100% load (2400 W) - up to 2 minutes
• 75% load - up to 3 minutes
• 50% load - up to 5 minutes
• 25% load - up to 17 minutes.

The batteries reach approximately 90% capacity after 5–8 hours of charging. The UPS can also work with the optional KU-BAT-2URT-4x9-BC48 external battery pack to extend backup time.

The RTS-LI-3K0-3U-LCD-4x9 protects connected equipment against the most common power problems, including power outages, surges, voltage drops, overloads, short circuits, overheating, battery overcharging, and deep battery discharge.

The automatic AVR system stabilizes voltage without switching to battery mode, extending battery life.

The UPS features a USB communication port for monitoring operating parameters and safely shutting down operating systems during prolonged power outages.

The device is compatible with UPSmart software (Polish and English versions) and supports Windows, Windows Server, and Linux operating systems.

Additionally, protected ports are provided for modem, telephone, and fax lines.

The RTS-LI-3K0-3U-LCD-4x9 is ideal for applications requiring reliable power protection, including server rooms and data centers, LAN/WAN networks, telecommunications equipment, CCTV and access control systems, industrial automation, measuring devices, PLC controllers, office equipment, drives, and control systems.
