Powerware’s 550 VA UPS

The look and feel of PW 5150 550 VA UPS from Powerware, is very attractive, given its sleek black-gray body. Even the LEDs and power switch on the front panel are arranged as a smiling face. Suitable for small offices and homes, the UPS has three LEDs for indicating mains availability, inverter status and UPS failures. The key features of the UPS include a built-in electronic voltage controller and network transient protector. It claims to support up to Intel PIII-based systems and has a rated back up time of 3 min at full load. The rated battery switch over time of around 6 ms also looks impressive.

It supports an input voltage range of 160-280 V AC. This means that it will not switch over to battery at these voltages, and yet keep your computer running happily. The output voltage range is +/-10% of 230 V AC, which is basically 207-253V. The UPS has alarms to indicate utility power failure, overload and low battery. There are four international type sockets for the load. There’s also a RS232 serial communication port to connect it to a PC. It comes with a power-management software CD for this. There’s also an RJ11 port for telephone surge protection. It has a single internal battery, which comes with one-year warranty. The UPS itself comes with a warranty of two years. You also get a 100 hours HCL Internet connection, students Britannica and 16 Indian language fonts. At Rs 5,000, the UPS seems an attractive buy.
