EVER parallel operation kit for Powerline Dark 33 [20-40 kVA] T/OP-ZAON-0022/00

EVER Powerline Dark 33 UPS – Reliable Power for Critical Applications

The EVER Powerline Dark 33 UPS is an advanced device with VFI topology (online, VFI-SS-111), designed to protect sensitive loads powered from a three-phase power grid. It is an ideal solution for server rooms, data processing systems, industry, and critical infrastructure where even short power outages can cause significant losses. The device is characterized by high efficiency and parallel operation capability, allowing for power scaling according to needs.

Key Features and Benefits

• Online Technology (VFI): Provides the highest level of protection by generating a stable output voltage regardless of voltage fluctuations in the grid. This means that connected devices are always powered by the UPS, not directly from the grid.
• Parallel Operation: The ability to connect up to four units allows for increased output power and redundancy – in the event of a failure of one power supply, the remaining units take over its load. This is especially important for large installations requiring continuous operation.
• High Efficiency: Efficiency levels of up to 95% (VFI) and over 99% (ECO) translate into lower operating costs and reduced energy consumption. ECO mode further optimizes power consumption during periods of stable power supply.
• User-Friendly Interface: A color touch LCD display with a Polish menu facilitates configuration and monitoring of the device status.
• Wide Input Voltage Range: Accepts input voltages in the range of 304-478 V, ensuring compatibility with various electrical installations.
• Advanced Communication Interfaces: RS232, RS485 ports and an optional SNMP/HTTP card enable remote monitoring and management of the power supply. A relay card and USB with a parallel operation card are also available.

Technical Parameters and Application

The Powerline Dark 33 power supply offers an apparent output power of 20 kVA (18 kW of active power). Its Tower design makes it easy to install and operate. Designed to operate at temperatures from 0 to +40°C, it has forced cooling with internal fans, ensuring reliable operation even under heavy load. The switchover time to backup operation is 0 ms – meaning no interruption in power to connected devices during a power failure. This makes it ideal for protecting servers, telecommunications equipment, medical devices, and other devices requiring uninterrupted power. It is also equipped with an EPO (Emergency Power Off) function for quick and safe disconnection from the grid.
