Battery Temperature Probe Installation

The temperature probe is used to monitor the battery string temperature. To get the most representative temperature measurement, the probe should be placed in contact with a battery cell that is centrally located. The probe should be placed directly in contact with the cell (not the frame surrounding the cell). Generally, the cell cover can be used; be careful not to allow the probe body to touch the terminals. Plug the connector end of the temperature probe into J410 of the backplane card. Route the cable as required positioning the probe on the selected battery cell. Remove the adhesive protection strip from the probe body and press the adhesive side of the probe on the battery cell cover. Refer to Figure 2.4-2 for details.

Note: Program Hardware Battery Temperature Alarm to “Ignore” if no battery temperature probe is connected to J410.

2.5.Counter Electro-Motive Force (CEMF) Cell Connections

WARNING: Hazardous energy levels are present on the CEMF connection area of the plant. Accidental shorting of conductors can cause arcing and high currents that can cause serious burns or other physical harm.

In some applications, a CEMF cell is used to lower the dc voltage delivered to the loads. The CEMF cell is mounted externally to the Magnum VS. The CEMF connections are located at the rear of the unit as shown in Figure 2.5-1. Two bus-plates, installed at the factory, bypass the CEMF connection. If a CEMF cell will be used, remove the bus plate connecting the two CEMF connection points and install two connection buses before installing the CEMF. The CEMF connection buses each provide a pair of #10-32 studs on 5/8” centers for connecting two- hole CEMF cable lugs. A ring size of 6 mm may also be used. Connect the CEMF cables as applicable using #10- 32 nuts.

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.
