1.1.General Information

The APC Magnum VS is a modular -48 Vdc power plant. The Magnum VS has unique features that make it easy to install, maintain, and upgrade. There are two Magnum VS models; Magnum VS 50 and 100. The Magnum VS 50 is a single shelf system and can support up to 5, 10A rectifiers, for a rated current of 50A. The Magnum VS 100 is a dual shelf system and can support up to 10, 10A rectifiers, for a rated current of 100A. The rectifier units are modular and “hot-swappable” making it easy to add or remove rectifiers as dictated by capacity requirements, without having to change the input or output wiring.

There are two basic DC output distribution options, circuit breakers (30A or 60A) or GMT-style fuses. The DC output distribution module also includes terminals to connect a battery string and a low voltage disconnect (LVD) device to disconnect the batteries after a deep discharge.

The system controller module provides monitoring and control functions for each component of the system, and stores alarm events for system diagnosis and maintenance. The system controller module enables the user to change/update Magnum VS settings, as well as monitor the system via a local computer directly connected to the Magnum VS system (using the serial cable provided by APC (please note that a standard serial cable cannot be used; the APC-provided serial cable must be used to connect directly to the Magnum VS system)), or a remote computer connected to the system over a network using a 10/100 Base-T Ethernet connection.

VS 50, VS 100 specifications

American Power Conversion (APC), a brand under Schneider Electric, is renowned for its uninterruptible power supplies (UPS) and provides a range of solutions for both commercial and personal use. Among their various product lines, the APC Smart-UPS 1000VA (VS 1000) and Smart-UPS 500VA (VS 500) stand out due to their features, technologies, and specifications tailored to different operational needs.

The APC Smart-UPS 1000VA is designed for advanced power protection, capable of supporting servers, network equipment, and more demanding applications. It features a pure sine wave output, which is critical for sensitive electronics, ensuring devices receive a stable and clean power source even during outages. The VS 1000 is equipped with an extensive battery backup, offering up to 9 minutes of runtime at full load.

A notable technology employed in the Smart-UPS 1000 is the Automatic Voltage Regulation (AVR), which maintains output voltage stability by adjusting boost and trim in situations of under or over voltage. The unit has an LCD interface, providing real-time data regarding load capacity, runtime, and battery health, enabling users to easily monitor and manage performance. Additionally, with its compact design, the VS 1000 can fit into various settings, maximizing space efficiency.

In contrast, the APC Smart-UPS 500VA targets smaller operations, offering a more compact solution for basic power protection needs. Like its larger counterpart, it also provides pure sine wave output, ensuring the safe operation of connected equipment. The VS 500 is designed for less intensive applications, making it suitable for desktop computers, network devices, and home office setups.

The 500VA model supports shorter runtimes, typically around 3 to 6 minutes under full load but is ideal for situations where downtime needs to be minimized. The Smart-UPS 500VA features similar Automatic Voltage Regulation technology, maintaining voltage stability under fluctuating conditions. However, it comes with a more straightforward LCD display, providing essential information on power status and battery levels without overwhelming the user.

In summary, the APC Smart-UPS 1000VA and 500VA cater to different user requirements, with the VS 1000 offering robust features for larger setups and the VS 500 serving as a versatile option for home or small office use. Both models integrate essential technologies such as pure sine wave output and AVR, showcasing APC’s commitment to high-quality power solutions. Whether for commercial or personal use, these units demonstrate APC's ability to provide reliable power protection tailored to diverse needs.
