2.9.Monitoring and Relay Output Connections

Front Panel DB9 Connection

The front panel DB-9 connector is used to hook up a standard RS-232 cable (such as APC part number 0129-XX. A 0129-6 is included with this manual. ). This will allow local access through a Terminal Emulation program such as HyperTerminal™ or ProComm. ™

RJ45 Ethernet Connector

The management card has an RJ-45 connector to support a TCP/IP protocol over a 10/100 BaseT Ethernet Local Area Network (LAN).

Major, Minor and Relay 1 Output Connections

There are three output relays available that provide outputs via Form “C” contacts. The output relays are named Minor, Major and Out Relay 1. Various system alarm conditions can be assigned to any of these three output relays. Most alarm conditions are shipped programmed to Minor or Major Relay. Wago connectors are located on the backplane card mounted in the left rear of the unit. Refer to the board layout in Figure 2.9-1 for Output Relay connections. The Wago connectors accept wires 26 AWG to 20 AWG (0.129 mm2 to 0.518 mm2). To connect the relay output, remove ¼ in (6 mm) of insulation from the end of the wire. Push down the white tab on the Wago connector, insert the stripped wire and release the tab to make the connection. The relay contacts should only be used to switch resistive loads of 0.5 A or less at 60 V or less. Figure 2.9-2 shows the alarm output connection designations. Whenever possible use the common and normally closed contacts. If the alarm wiring gets pulled loose, or the controller is removed, you will get an alarm. The Major relay is energized (C-NO contacts closed) during normal (non-alarm) operating conditions; the other relays energize when an alarm condition occurs. If your Major relay wiring uses the C-NO contacts, then a major relay output will be seen whenever the controller is removed from the shelf.

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.
