System Current Monitor

The controller monitors individual rectifier currents and displays total system current as a sum of rectifier currents. Load current can be found by adding battery current to system current. Battery Current is positive when the battery is discharging.

Sys Current + Batt current = Load Current

For example, if the battery is charging the Batt Current reading could be (–) 10 A, Sys Current reading could be 50 A. Load Current would be:

Sys Current + Batt current = Load Current 50 A + (-) 10 A = 40 A.

If the battery is discharging the Batt Current reading could be 10 A, Sys Current reading could be 30 A. Load current would be:

Sys Current + Batt current = Load Current 30 A + 10 A = 40 A.

System Status and Alarm Reporting

The controller will monitor system, temperature. The controller reports system high and low temperature alarms.

4.3.Load Management

Circuit Breakers

The Magnum VS Distribution Module includes two (2) 30A or one (1) 60A circuit breaker, or eight (8) GMT fuses. When a circuit breaker trips, a normally open switch closes and the Controller reports a CB alarm. Alarms are reported only when a breaker is tripped. When a breaker is turned off, no alarm is generated. Circuit Breaker Alarms 1 or 2 are reported when a circuit breaker in the top shelf trips. Circuit Breaker Alarms 3 or 4 are reported when a circuit breaker in the bottom shelf trips. Please note that if a Magnum VS 100 system has one (1) circuit breaker in the top shelf and one (1) circuit breaker in the bottom shelf, the circuit breakers in the bottom shelf will be labeled CB2 on the front panel, but Circuit Breaker Alarm 3 will be reported. To disconnect a load attached to a circuit breaker, move the lever down to the “OFF” position.

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.
