The Qoltec low frequency Pure Sine Wave online UPS emergency power supply is designed for use in the most demanding industrial and server applications. It will provide your device with clean energy at a constant output voltage and frequency, as well as comprehensive protection when powering even the most sensitive devices. The design, which uses an isolation transformer, ensures a high level of protection against interference, surges and power grid failures.
Its features include:
- Pure sine wave,
- Zero switching time,
- Double conversion,
It will meet the requirements of anyone who wants to be in control regardless of mains power fluctuations,
Built-in SNMP module.
Your reliable partner in maintaining the continuity of your equipment's operation
Complete protection against power outages
The most advanced type of UPS, which provides complete protection against power outages by regulating and stabilising the voltage at all times, making it ideal for sensitive equipment. Online UPS has a voltage that is constantly processed. In the event of an unexpected drop in mains voltage, the power supply unit keeps the connected device running. This is possible after installing appropriate batteries, which will be charged on an ongoing basis. Mains power is only needed to charge the batteries. Devices permanently connected to the power supply always receive clean energy without interference.
PURE SINE WAVE - THE HIGHEST QUALITY AND SAFETY FOR POWERING YOUR DEVICES
Zero switching time, high system efficiency, double conversion, ECO mode, transformer isolation
The Qoltec 20kVA UPS power supply is distinguished by:
- pure energy with a sinusoidal waveform free of interference,
- zero switching time, i.e. the speed at which the UPS switches to battery mode in the event of a power failure
- protection against overload, short circuit and overheating,
- double conversion – stable power supply,
- built-in service bypass – for trouble-free maintenance of the device,
- RS-232 port – a communication bus designed for serial data transmission,
- EPO interface - a function that allows remote shutdown of the power supply in emergency situations,
- built-in SNMP module,
- 2 fans - provide intensive cooling of the device during continuous operation,
Advanced Low Frequency technology for maximum efficiency
Highest Power and Reliability - Low Frequency Technology
The device utilises a low frequency transformer that operates at mains frequency (50/60 Hz). The UPS is more resistant to overloads and current surges, and is more durable mechanically and electronically. Designed to work with demanding loads (motors, compressors, pumps, servers with high start-up power consumption).
The clear LCD screen provides all the necessary information about the status of the device, operating parameters, battery charge level and settings.
Pure sine wave – the highest quality and safety for powering your devices
Stable, clean, sine wave power without interference for complete protection of your devices
Qoltec UPS power supplies provide stable, interference-free, pure sine wave power. They offer complete protection for your devices thanks to double conversion, which first converts the mains AC power to DC power and then to AC power, ensuring the highest level of power quality and protecting against potential mains disturbances such as voltage drops, power failures, surges and failures.
Manage your power supply with ease thanks to the clear LCD display.
The integrated LCD display ensures intuitive operation and monitoring of power supply parameters
The integrated LCD display makes device management intuitive and convenient. The screen provides you with up-to-date information on the operating status and key parameters of the power supply unit. This ensures that you are always up to date with the operation of the device, enabling you to respond quickly to any problems and optimise its operation to your needs. Working with the power supply becomes easy, fast and reliable, allowing you to focus on your main tasks without worrying about power stability.
Ready for the biggest energy challenges
Industrial technology for demanding users – Ideal for businesses, server rooms and industry
Thanks to double conversion technology and an isolation transformer, it provides complete protection for sensitive electronics, medical systems, modern machinery, office equipment and network infrastructure. It is the ideal choice for companies that expect maximum uptime, high-quality power and complete reliability. It is perfect for data centres, server rooms, production facilities, laboratories, telecommunications and anywhere where even a momentary interruption in operation can cause losses or safety hazards.
Quick response in emergency situations
Built-in EPO module
The power supply is equipped with an easily accessible EPO (Emergency Power Off) module, which allows you to completely cut off the power supply with a single button in emergencies, such as fire or flooding. It cuts off both the battery and mains power supply, which is essential for safety.
