Product Review (April 2005)
Belkin - Office Series 750VA UPS (F6C750-AVR)
and Universal 800VA UPS (F6C800-UNV)

Belkin has a full line of Uninterruptable Power Supplies (UPS) ranging from their 375VA UPS ($43.99) to the 1500VA Dual Form Factor Small Enterprise model ($199.99). They even offer a 1400VA pure sine wave version ($599.99) for those who need an ideal power signal. We looked at a couple of their low-cost UPS models for this review. The Office Series 750VA UPS (model F6C750-AVR) is a compact design that offers power backup protection from brownouts and blackouts. The unit is designed to handle loads as high as 400 watts, which works great for most PCs (including monitor) as well as some home electronics. Four of the six outlets are fully protected from power outages using the internal battery backup, while the remaining two outlets are only protected from voltage surges. The design features Automatic Voltage Regulation (AVR) for line conditioning and protection against brownouts, during which the voltage sags momentarily. The back of the unit has three RJ11 Telephone/Fax Surge Protection jacks (1-In, 2-Out) to protect connected phone line equipment. A USB port is also available for connecting the unit to a computer for complete monitoring and controlling capabilities.

The front panel has a power button and three LEDs for status. The green Power LED indicates power is on and begins to flash if the AVR circuitry kicks in. The yellow On Battery LED illuminates when power is interrupted and the UPS is running from the batteries or if the battery power is running low. The red Fault/Overload LED comes on if there is a problem with the unit or if the battery is weak or bad. It will begin to flash if the load is too high. The red rear panel LED lights up if there is a wiring problem, such as reversed hot/neutral or a floating ground.

Monitoring Software
The Belkin Bulldog Plus Monitor software included with the unit provides the user with the ability to monitor vitals such as input and output voltages, loading level, messaging, diagnostic support, history event logs, scheduled shutdowns, and log management.

The scroll screen displays the voltage history just like a strip chart recorder from the old days. Users can see both the input voltage and output voltage together on a single screen. Once a power failure has been detected, the software launches a broadcast message that counts down from 5 minutes. This gives users enough time to save critical data. The F6C750-AVR also includes a $75,000 Connected Equipment Warranty, a Data Recovery Warranty, and a 3-Year Product Warranty (See manufacturer for details). The Office Series 750VA UPS (F6C750-AVR) retail for $109.99 making it very affordable.

The Universal UPS 800VA is another affordable UPS that has a slightly higher output rating than the Office Series 750VA mentioned above. The 800VA UPS is designed to handle loads as high as 450 Watts and is noticeably heavier than the 750VA UPS. Like the Office Series 750VA, four of the six outlets are fully protected from power outages and the remaining two outlets are only protected from voltage surges. The Automatic Voltage Regulation (AVR) circuitry is also included in this design to protects against brownouts. The rear panel has two RJ11/RJ45 Surge Protection jacks (1-In, 1-Out) that protect phone or computer LAN equipment. A USB port and RS232 port offer a bit more flexibility than the earlier UPS, yet the same Bulldog Plus software is used to monitor, control and configure the unit. The F6C800-UNV also includes a $150,000 Connected Equipment Warranty, a Data Recovery Warranty, and a 3-Year Product Warranty (See manufacturer for details). The Universal 800VA UPS (F6C800-UNV) retails for $119.99, only $10 more than the 400 watt model. The same set of LED indicators are present on this unit providing the user with information about the state of the UPS.

Modified Sinewave Output
Both models reviewed here generate modified sinewave AC waveforms when running on batteries. These outputs have the advantage of simplifying the electronics within the UPS unit, yet can cause problems with some electronic components. Rather than rising slowly and falling slowly following the sine function, these units switch between a V+ voltage, ground and a V- voltage. By controlling the amount of time the pulse is positive and then negative, the UPS can create an effective RMS voltage similar to the incoming utility power.

Conclusion
Belkin's new 750VA (400 watt) and 800VA (450 watt) UPS units provide an economical way of insuring continuous power to critical products in the event of a brownout or complete power failure. Both systems worked very well and the Bulldog Plus software included with the units provided us with complete control over the UPS
. The downside to these type of power inverters is the modified sinewave output. True sinewave designs are available, but are considerable more expensive. If you can live with a modified sinewave UPS, these units offer exceptional value and performance.
