Uninterruptible Power Supply PowerWalker VFI 15K CPG PF1 3/3 BE Double-conversion (Online) 15 kVA 15000 W Tower Black LCD

PowerWalker VFI 15K CPG PF1 3/3 BE is a double-conversion (Online) uninterruptible power supply that provides 15 kVA (15000 W) of continuous output power in a tower form factor. Designed for data centres and enterprise environments, the UPS features an LCD display, 12 V battery configuration with adjustable battery number, an integrated USB 2.0 port and a black enclosure. The unit uses three-level inverter topology and Unity Power Factor (kVA = kW), delivering a pure sine waveform and precise voltage regulation for critical IT loads.

Advantages

The VFI 15K CPG PF1 3/3 BE offers full double-conversion protection, ensuring continuous regulated AC output regardless of input disturbances. High efficiency is achieved through a three-level inverter design, with up to 95.5% in Line Mode and up to 98.5% in ECO Mode, which reduces energy losses and operating costs. Built-in SNMP support, generator compatibility, dual input and the ability to operate in parallel up to three units provide flexibility for monitoring, expansion and integration into existing power infrastructures. Adjustable battery count and three-stage extendable charging enhance battery lifetime and allow compatibility with different external battery banks.

Suitable for

• Server rooms and data centres requiring continuous regulated power
• Enterprise network equipment, switches and storage systems
• Critical IT loads and communications infrastructure
• Environments needing scalable redundancy through parallel operation

When it may not be suitable

This UPS is designed for medium to large IT installations and may be oversized for small home offices or single desktop workstations where a lower-capacity UPS would be more cost-effective. The tower form factor and weight (around 43 kg unit weight, packaged heavier) require sufficient floor space and handling considerations, so it may not be appropriate where strict space or weight limitations exist.

How to use

Install the UPS on a stable floor surface with adequate ventilation and ensure clearance around the unit for cooling. Connect the mains input and, if used, a generator input according to site wiring practices; the UPS supports dual input. Fit and configure the required number of 12 V batteries to achieve desired runtime, and set the charging and battery parameters via the LCD touch panel or management software. Use the built-in SNMP card for network monitoring and management; connect the USB 2.0 port for local communication when needed. For increased capacity or redundancy, configure parallel operation with up to three identical units following the manufacturer’s parallel installation procedure.

What to consider before purchase

• Required runtime and battery configuration — determine number of 12 V batteries needed for target backup time
• Physical space and weight limitations at the installation site
• Cooling and ventilation requirements for continuous operation
• Integration needs such as SNMP monitoring, generator support and parallel expandability
• Compatibility with existing battery banks if retrofitting

Usage recommendations

For reliable operation, install the UPS in a temperature-controlled environment, perform regular battery tests and follow the recommended charging settings. When deploying multiple units for redundancy, use identical models and match battery configurations to ensure balanced parallel operation. Use the SNMP management functions to integrate the UPS into existing monitoring systems for early detection of issues and scheduled maintenance.
