Ups Accessories and How They Bolster Power Protection

To enhance the workability, functionality and reliability of the UPS system, accessories also play a vital role in adding value and overall resilience. UPS accessories include software, adapters, sensors, cable converters, interface panels and bypasses, all purposely designed to work alongside UPS and for implementation in power protection applications.

Software:

Most reputable uninterruptible power supply manufacturers provide user-friendly management and monitoring software. UPS software displays real-time information in the form of bar charts and values explaining critical data such as mains voltage, UPS load and battery charge percentage.

UPS Software enables remote interrogation of logs and operating parameters to help diagnose alarms and potential fault conditions. When instructed, it performs an automated safe power down of protected loads (PCs and file severs, for example) to safeguard them against damaging and costly system crashes.

Adapters:

Network Management Protocol (SNMP) adapters, USB converters, duplexers and protocol converters expand the communications capabilities of uninterruptible power supplies and provide ease of management across networks and multi-operating platforms.

These devices are usually bespoke-designed for specific customer projects.

A network agent (such as Riello UPS’s NetMan) allows UPS management across a LAN using any of the main network communication protocols – TCP/IP, HTTP and network interface (SNMP). Network agent-enabled uninterruptible power supplies integrate easily into medium and large sized networks and provide reliable communication between the UPS and management systems that are employed therein.

Cable and Protocol/Converters:

Protocol converters (such as Riello UPS’s MultiCOM) may be used to monitor the UPS using the MODBUS/JBUS protocol on RS485 or RS232 serial lines. It will also manage a second, independent RS232 serial line that can be used to connect other devices such as the network agent or PC running the uninterruptible power supply management and monitoring software.

The device integrates the UPS with control systems and offers complete configurability of the input and output signals. The RS232-USB converter allows uninterruptible power supplies without a USB port to connect to Macintosh, Windows and Linux PCs (provided they have a USB port).

Sensors:

Uninterruptible power supplies and UPS batteries in particular, are susceptible to changes in the environment so sensors that keep a check on temperature and humidity are advisable to be used in a power protection system. UPS batteries, in particular, must be stabilised at an ambient temperature of 21-25 degrees centigrade. Even so much as one degree above or below this threshold can seriously diminish the design life of UPS batteries.

Panels:

The panels that sit on the front of the uninterruptible power supply unit and act as the operator interface need to be clear, visual, easy to operate and understand plus robust enough to withstand their environment (whether heavy industrial or dynamic IT sites).

In addition, some manufacturers offer a remote monitoring panel designed to provide a detailed overview of the UPS to which it is connected. This panel can provide a range of useful operating information (in a variety of languages – depending upon operator preference) including specific UPS input and output voltage and frequency values and status information on the UPS battery set.

Riello UPS’s MultiPanel, for example, has three independent serial ports – one for UPS monitoring using the MODBUS/JBUS protocol (either an RS485 or RS232 serial line) and others designed for use with UPS accessories such as network agents and UPS monitoring and control software.

When selecting a panel it is advisable to choose one that is compatible with most building management systems, and that has a communications flow LED status indicator and the capability for firmware upgrade via one of its serial ports.

Bypasses:

In this day-and-age of continuous uptime and 24/7 operating environments, an uninterruptible power supply maintenance bypass is a must. It allows a UPS unit to be powered down for maintenance without disruption to the load and is typically installed with on-line power systems from 700VA to 800kVA. Many bypasses available from reputable UPS manufactures are ‘plug and play’ with a range of socket configurations, and are usually available in wall mounting and 19″ rackmount formats so as to be able to be sited in server racks alongside computer loads. An additional safety feature is an automatic transfer should the output of the UPS fail due to overload, system fault or accidental disconnection.

So, with uninterruptible power supplies it is wise to accessorise but select carefully. Compatibility is key. Choose accessories that are most closely related to the actual UPS system itself. Sourcing from the same manufacturer is recommended.

HVAC Estimating Software – a Buyers Guide

HVAC estimating software is fast becoming the way contractors figure out what things cost and give estimates to clients who want to crunch the numbers of their next product. Contractors use it a lot so they can also figure the profit they can make from a job when cost is figured in. There are many different types of HVAC estimating software out there so knowing what you need in a program can be vital to your business success. Let us look at some things that you want to make sure your software has with it.

One of the first things that you should look for is setup and configuration of any HVAC software. There is no sense of buying something that will take you forever to master as in the long run that will just cost you more money and time. When time is money you want to be able to use the software quickly and efficiently. The second thing that you want to make sure it has and that is plenty of ways to estimate what a job will run you. Many times certain jobs that you will do will only need certain things done so the ability to figure out costs on small jobs as well as big jobs is very important.

Breaking down all the elements as far as costs, taxes, labour in convenient forms is very important. Many times a customer may want to see what something will cost them on paper and this can be a vital step to closing a job. Having HVAC software that can handle that is very important. Support of the software is also something that you will want to make sure you have. There will be times that you have a question about a certain aspect of the software and you need quick answers to these questions so it does not slow down your business operation. Time is money and any down time could cost you money which will not make you very happy.

Software that is also portable and can be transferred through many channels is also something you should look for. Many people are always on the road and the ability to access it from a remote point is something that you should be able to do. Customers a lot of times want an estimate right now and will not wait so being able to have that ability could close the sale very quickly. It must also be user friendly for the person who is not really computer savvy. Not everyone is great with computers especially if they are out in the field so have a HVAC software package that is very easy to understand and operate will make your business run much smoother as well.

There are many different types of HVAC software and each one has different things so finding the perfect one for you depend on what you need it for. Study each one before making your decision on which will work best for you.
