The APC Galaxy VS is a modular, three-phase online UPS with double-conversion technology, designed for a rated power of 20 kVA and an active power of 20000 W. The device is intended for use in critical IT and industrial applications where continuous, uninterrupted power supply is required. The UPS operates in online mode, ensuring that the output voltage remains stable regardless of the input voltage. The output voltage ranges from 340 V to 460 V, and the frequency is regulated to 50/60 Hz, ensuring compatible power supply for sensitive equipment. Voltage regulation is ±3 %, guaranteeing high stability of the output voltage. The maximum current is 36 A, and the output THD (total harmonic distortion) is 5 %, ensuring a clean sine wave. The input power factor is 0.99, enabling efficient use of the mains voltage. The input THD is 6 %, minimizing grid load. The device features an ECO mode that increases efficiency when the mains voltage is stable. The noise level is 54 dB, which is acceptable for industrial use. Integrated acoustic signals indicate operating status and faults.

Applications
The APC Galaxy VS is suitable for use in data centers, industrial facilities, medical institutions, and other critical infrastructures where power interruption is not acceptable. The modular design allows for flexible scaling and redundancy. The UPS is designed for an operating temperature of 0 to 40 °C and a relative humidity of 0 to 95 %. The maximum operating altitude is 1005.8 m, and the storage altitude can reach up to 3048 m. The IP20 protection rating protects against finger contact and solid foreign objects, but is not suitable for outdoor use or humid environments.

Features and Equipment in Detail
The device includes an LCD display showing operating status, battery charge levels, and error messages. The battery technology is based on sealed lead-acid (VRLA) batteries with a voltage of 480 V DC. The charging current is 54 A. The UPS is designed for up to five intelligent modular 9-Ah battery strings, which must be purchased separately. Batteries are not included in the delivery scope. The modular architecture enables N+1 redundancy by adding an extra power module, increasing availability. The UPS is designed for an input voltage range of 340 V to 460 V, with a typical operating voltage of 400 V. The output voltage also ranges from 340 V to 460 V, with 400 V as the standard value.

Technology Explained Simply
Double-conversion technology ensures that power continuously flows through the UPS, regardless of the mains voltage. This guarantees immediate power supply in case of a mains failure, without any transition time. The sine wave output is essential for sensitive equipment such as servers, network equipment, and medical devices, as it avoids causing disturbances. Voltage regulation of ±3 % ensures that the output voltage remains stable even during fluctuations in the mains supply. The ECO mode partially switches the UPS to bypass mode when the mains voltage is stable, increasing efficiency. THD values (5 % output, 6 % input) indicate that the voltage waveform is clean and grid load remains low.

Compatibility and Accessories
The UPS is designed for use with intelligent modular 9-Ah battery strings, supporting up to five strings. These batteries must be purchased separately. The device is designed for N+1 redundancy, requiring an additional power module. Certifications IEC 62040-1-1, IEC 62040-2, and OSHPD confirm compliance with international standards for safety, performance, and use in medical facilities. The quick installation guide is included in the delivery scope.

Installation and Mounting
The UPS has dimensions of 550 mm (width) × 847 mm (depth) × 197 mm (height) and weighs 250 kg. Installation requires a suitable location with sufficient clearance from other devices for ventilation. Mounting is typically done in a rack system or on a foundation, with electrical connections to the three-phase supply and the load. Commissioning can optionally be performed with a 5x8 service, which is not included in the delivery scope.

Operational Advantages
The modular design enables flexible scaling and redundancy, increasing availability. Double-conversion technology ensures immediate power supply without transition time. High efficiency in ECO mode reduces energy consumption. Integrated batteries at 480 V DC and support for up to five 9-Ah modules provide sufficient backup time. Certifications ensure suitability for critical applications. The LCD display and acoustic signals facilitate monitoring and fault diagnosis.

Storage Note
The device can be stored at temperatures from -15 to 40 °C and relative humidity from 0 to 95 %. The maximum storage altitude is 3048 m. Packaging dimensions are 755 mm (width) × 1010 mm (depth) × 2082 mm (height), and the package weight is 250 kg. The HS code is 85078000.
