APC Smart-UPS 1000VA USB & Serial 230V

Product Information

For some single phase UPS with runtimes up to 7-8 hours or more and for three phase UPS, extended battery runtimes are provided in external battery extension cabinets or on open or closed (cladded) stands. For operational safety, battery testing and maintenance battery transition boxes (BTBs) may be used for multiple battery strings and each cabinet/string will be fuse/circuit breaker isolated. UPS Battery Calculations

This means that whilst a UPS system can produce 100kVA of power. The equipment being powered by the generator can only use 80% of it (80kW at 0.8 power factor). We've tested these UPS machines across numerous points, starting with what environment they're best suited for — home, small office, or server farm?The calculation is an approximate value because battery discharge curves are non-linear. UPS systems use complex algorithms to determine the runtime available for a set Ah battery size connected and the measure load placed upon them. This information can be read on the front panel LCD or remotely via an SNMP Ethernet/IP connection using remote UPS monitoring software. It’s very difficult to say with any precision how much time you’ll have, because of another complicating factor: the non-linear nature of a UPSbattery’s discharge. The power-capacity and the rate of discharge don’t correlate evenly; small changes in the former can produce big changes in the latter.

The general formula for calculating the runtime available from a UPS battery is: (10 x Battery Ah) / Load Watts. The Ah (Ampere-hour) of a battery is the amount of energy (charge) stored in a battery. The Ah measures the rate of electron flow to allow 1 Amp (ampere) to flow for 1 hour. If you want to be especially safe, you can automate the shutdown process via a USB or RS-232 connection. In a setup like this, the UPS will instruct your servers to shut down the moment the power goes out. This saves you the trouble of racing into the office to save your data and eliminates the opportunity for human error. What UPS should I choose?

If a 250W load is placed on a 1000VA UPS with a 12Ah battery, then (10 × 12)= 120 / 250 = 0.48 hours x 60 = approximately 29 minutes. Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. Full time multi-pole noise filtering : 0.3% IEEE surge let-through : zero clamping response time : meets UL 1449 Then, you'll want to assess how much power your devices require and how much time you need the electrical supply for once there's a power cut. If your device takes a few minutes to turn off, make sure to select a UPS system that can provide sufficient runtime for that. The best UPS: How we test

Stable Output

A 1000VA UPS might be able to power a small office computer for around sevenminutes. Make the upgrade to a 10kVA UPS, and you might see this figure jump up to around twenty-sevenminutes. Go too small, on the other hand, and the available time shrinks to just a few minutes or less. Is it better to go bigger?

The load measured in Watts is referred to as the Real Power and is the total Watt load placed on the uninterruptible power supply. A load may also be measured in VA (Volts x Amps) or kVA. VA measures the Apparent Power.The kVA-rating determines the total amount of power that the device can supply at any one time, but this needn’t imply anything about how long the supply will last for. A UPS is designed to safeguard sensitive equipment and afford you the time required to shut everything down properly. What it isn’t designed to do is ‘ride-out’ a power-cut; there is only a finite amount of power stored within a UPS and a power-cut could be a long-term problem. The solution to a mid to long-term disruption would be a generator. If you’d like to immunise your business against protracted outages, then a generator system and a UPS make excellent partners: together, they’ll keep the lights on for extended periods. What about the automatic shutdown? The equipment connected to the UPS is drawing more power than the UPS can provide. Each model of UPS is capable of handling a predetermined amount of power draw. Verify that the wattage draw from your equipment plugged into the outlets does not exceed the Watt rating.
