SYSTAT - Critical Systems Protection Services

SYSTAT sells, tests and maintains battery systems for UPS, Lighting Inverters, Rectifiers and start batteries for back-up power generators. We only install newfresh batteries manufactured less than 90 days prior to installation. The batteries we sell and install come with a 3 year warranty from the manufacturer. If your system is under a SYSTAT Service Agreement we will also cover the cost of labor for warranty replacements. We supply batteries and battery packs for brands including APC, Toshiba, Powerware, Eaton, and many more. We understand your needs so if you are not sure what product you want to buy, please call us at 888.782.8498. We will guide you in selecting the right battery for your equipment.

GenWatch reduces the probability of a failure to start by about 90%. It directly monitors the important voltages and key parameters in the generator and does not require an interface with any of the generator's existing electronics. As a result, it works with any generator. When the generator needs attention - or changes its status in a meaningful way - GenWatch reaches out directly via text messages to the personnel who are responsible for the generator. It also automatically creates a permanent runtime log that meets the requirements of air quality control authorities.

An uninterruptible power supply (UPS) is an electrical apparatus that provides emergency power to a load, when the input power source, typically mainspower, fails. A UPS provides near-instanteneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or fly-wheels. The on-battery runtime of most UPS's is relatively short but sufficient enough to start a standby power source or properly shut down the protected equipment. A UPS is typically used to protect hardware such as computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 volt-ampere rating) to large units powering entire data centers or buildings. OnlineDouble-Conversion In an online UPS, the batteries are always connected to the inverter, so that no power transfer switches are necessary. When power loss occurs, the rectifier simply drops out of the circuit and the batteries keep the power steady and unchanged. When power is restored, the rectifier resumes carrying most of the load and begins charging the batteries, though the charging current may be limited to prevent the high-power rectifier from overheating the batteries and boiling off the electrolyte. The main advantage of an on-line UPS is its ability to provide an "electrical firewall" between the incoming utility power and sensitive electronic equipment. The online UPS is ideal for environments where electrical isolation is necessary or for equipment that is very sensitive to power fluctuations. Although once previously reserved for very large installations of 10 kW or more, advances in technology have now permitted it to be available as a common consumer device, supplying 500 W or less. The initial cost of the online UPS may be higher, but its total cost of ownership is generally lower due to longer battery life. The online UPS may be necessary when the power environment is "noisy", when utility power sags, outages and other anomalies are frequent, when protection of sensitive IT equipment loads is required, or when operation from an extended-run backup generator is necessary. The basic technology of the online UPS is the same as in a standby or line-interactive UPS. However it typically costs much more, due to it having a much greater current AC-to-DC battery-chargerrectifier, and with the rectifier and inverter designed to run continuously with improved cooling systems. It is called a double-conversion UPS due to the rectifier directly driving the inverter, even when powered from normal AC current. Offline Standby The offlinestandby UPS (SPS) offers only the most basic features, providing surge protection and battery backup. The protected equipment is normally connected directly to incoming utility power. When the incoming voltage falls below or rises above a predetermined level the SPS turns on its internal DC-AC inverter circuitry, which is powered from an internal storage battery. The UPS then mechanically switches the connected equipment on to its DC-AC inverter output. The switchover time can be as long as 25 milliseconds depending on the amount of time it takes the standby UPS to detect the lost utility voltage. The UPS will be designed to power certain equipment, such as a personal computer, without any objectionable dip or brownout to that device. Line-interactive The line-interactive UPS is similar in operation to a standby UPS, but with the addition of a multi-tap variable-voltage autotransformer. This is a special type of transformer that can add or subtract powered coils of wire, thereby increasing or decreasing the magnetic field and the output voltage of the transformer. This is also known as a Buck–boost transformer. This type of UPS is able to tolerate continuous undervoltage brownouts and overvoltage surges without consuming the limited reserve battery power. It instead compensates by automatically selecting different power taps on the autotransformer. Depending on the design, changing the autotransformer tap can cause a very brief output power disruption, [5] which may cause UPSs equipped with a power-loss alarm to "chirp" for a moment.
