It is designed specifically for enterprise and industrial applications requiring three-phase power.

Key specifications

• Power capacity: 20kVA / 16kW
• Topology: 3-phase on-line double conversion, low frequency
• Output waveform: Pure sine wave
• Interfaces and management: LCD display, USB connectivity, SNMP slot, EPO (Emergency Power Off)

How to use

Installation and setup of the Qoltec 3-phase on-line UPS should be performed by qualified electrical professionals in accordance with local electrical codes and manufacturer guidelines. Connect the unit to an appropriate three-phase mains power source and securely attach the critical load equipment to the designated output terminals. Configure network monitoring settings using the USB connection or an optional SNMP card to enable remote status tracking and alerts. Perform initial system checks via the LCD control panel to verify operating parameters, battery status, and load levels before putting the system into full operational service.

What to consider before purchase

• Verify that your facility has adequate three-phase electrical infrastructure to support the unit
• Assess the total power consumption of your connected devices to ensure it remains within the 16kW limit
• Measure the physical installation space and account for the weight and ventilation requirements of a low-frequency UPS system
• Determine if additional accessories, such as SNMP cards or external battery cabinets, are required for your specific operational needs

Regularly monitor system metrics through the LCD display and remote management interfaces, schedule routine professional maintenance inspections, and test the emergency power off functionality periodically to ensure maximum reliability and extended service life of the UPS unit.
