UPS power supply EVER Powerline Green 20-33 PRO (9Ah) W/PGRPTO-3320K0/09

UPS EVER Powerline Green 20-33 PRO – reliable power supply for sensitive devices.

The EVER Powerline Green 20-33 PRO UPS is an advanced On-Line (VFI) class device designed to provide uninterrupted power to particularly sensitive receivers such as servers, computer networks, data processing systems and industrial equipment. The device is characterized by high efficiency, quiet operation and a range of protections that protect both the power supply itself and the devices connected to it. It is an ideal solution for companies and institutions that cannot afford interruptions in power supply.

Design and functionality

The power supply uses VFI topology (online, VFI-SS-111), which means it constantly processes the mains voltage, providing a stable and clean power supply to connected devices. This makes it resistant to voltage fluctuations, disturbances and other problems with the power grid. Additionally, the device offers hybrid operation – in the event of a deterioration in the parameters of the mains voltage, it can continue to operate, drawing energy from both batteries and the mains. This extends the autonomous operating time and ensures the continuity of critical systems.

The applied dynamic cooling control algorithm optimizes the operation of the cooling system depending on the current load on the device. This minimizes power losses and cooling costs. Intelligent Battery Management (IBM) technology takes care of the battery life by optimizing the charging and discharging process. The Start-on-battery function allows the UPS to be started even without available mains power – so-called cold start.

Safety and protection

The EVER Powerline Green 20-33 PRO UPS is equipped with a number of protections to protect both the device itself and the connected receivers:

• Overload: protects against damage caused by excessive load.
• Short-circuit: immediately cuts off the power in the event of a short circuit.
• Thermal: prevents the device from overheating.
• Overvoltage: protects against the harmful effects of overvoltages in the power grid.
• EPO (Emergency Power Off): allows remote emergency power off in crisis situations.

Additionally, the device logs events and analyzes environmental parameters such as temperature and humidity, allowing monitoring of the UPS operating status and the environment. High short-circuit current ensures high selectivity of protections on power distribution lines.

Key product features:

• On-Line operation: Provides the highest power quality thanks to real double conversion of the output voltage with a sinusoidal waveform (VFI‑SS-111).
• Reactive power compensation: Allows reducing electricity costs by reducing charges for reactive power consumption.
• Quiet operation: Thanks to the use of ultrasonic switching frequency, the device operation is almost silent.
• Scalability: Possibility of extending the autonomous operating time by connecting additional battery modules and scalability of the power supply.
• Intelligent battery management: IBM technology extends battery life and optimizes their operation.
• Wide voltage window: Allows operation even with large voltage fluctuations in the power grid.
