Qoltec 3-phase UPS | 20kVA | 20kW | LCD | EPO | USB | Power factor 1.0

Excellent performance and reliability

Our Uninterruptible Power Supply 20kVA/20kW 3-phase is an advanced device that provides you with the highest stability and pure sine wave continuous power supply. Ideal for companies and businesses that cannot afford downtime, the UPS operates online and offers excellent performance with a power factor of 1.0 on both input and output. ECO mode optimizes energy consumption, reduces operating costs and ensures the highest level of efficiency. BYPASS, Battery Mode and AC Mode provide flexibility, adapting to the power needs of different situations. Regardless of the circumstances, your installation is safe.

- Pure sine wave - the best quality and safe power supply for your devices
- Stable interference-free clean energy with a sine wave shape
- Qoltec brand 3-phase UPSs provide stable, interference-free, clean energy with a sine wave shape. It provides complete protection for your devices with double conversion, which first converts the AC power supply voltage to DC and then to AC, ensuring the highest level of power quality and protecting against possible network disturbances such as voltage drops, power outages, surges and failures.

Quick response in emergencies

The power supply is equipped with an easily accessible EPO module (Emergency Power Off), which allows you to completely disconnect the power supply with a single button in an emergency, such as fire or flood. It disconnects both the battery and the mains power, which is essential for safety.

Clean energy, no interference

The most advanced UPS type, providing complete protection against power outages, continuously regulates and stabilizes the voltage, making it ideal for sensitive devices. The voltage of the UPS Online can be continuously recycled. In the event of an unexpected drop in the mains voltage, the power supply maintains the operation of the connected device. This is possible after installing the appropriate 12 V batteries (16 pcs), which are constantly charged. The power from the mains is only needed to charge the batteries. Devices that are permanently connected to the power supply always receive clean energy, without interference.

Zero switching time, double conversion

The Qoltec 20 kVA 3-phase UPS is an advanced device that provides safe, uninterrupted power supply and full protection for your equipment. It offers:
- interference-free sine-shaped clean energy,
- zero switching time: the speed at which the UPS switches to battery mode in the event of a power outage
- protection against overload, short circuit and overheating,
- double conversion - a power supply with stable parameters,
- cold start - in the event of a power outage, you can turn on, for example, a computer by connecting it to the UPS itself. This allows you, for example, to quickly copy important files to a USB drive or send an important e-mail at any time,
- Built-in service bypass - For trouble-free maintenance of the device,
- RS-232 port and RS-232 cable - a communication bus for serial data transmission,
- EPO port - Allows emergency shutdown,
- Four fans - Ensures intensive cooling of the device during continuous operation.

Transparent LCD display
The easy-to-read LCD screen provides all the necessary information about the device status, operating parameters, battery charge level and settings. Thanks to the intuitive user interface, managing the UPS becomes simple and efficient.
