Tools and Hardware Reviews of Xantrex Technology 851-0400 XPower Plus 400-Watt InverterCustomer Review: Beware of the 60 +/-4 Hz frequency specification Summary: 2 StarsSeveral of the Xantrex inverters including this one have much looser frequency specs compared to the last generation of inverters which were typically 60 Hz +/- 0.01%. Many of the current crop of these inverters have 60 +/-4 Hz which is 60 Hz +/- 7%. To be fair, I've noticed a number of inverters made by other companies also have relaxed this spec. I measured the output frequency of several models and found their outputs to range from 58 Hz to 64 Hz. I didn't test to see if the frequency changed with temperature, input voltage, load, or other other factors. I suppose the reason for this change in specs is that these manufacturers are now cost cutting to the extent of eliminating a 30 cent quartz crystal. The frequency variation is most likely to cause problems (speed changes and overheating) in devices with AC motors, but it will also cause inaccuracies in devices that use the AC line frequency for timing purposes.
Description of Xantrex Technology 851-0400 XPower Plus 400-Watt InverterSTATPOWER 300 WATT The Xantrex Technologies XPower Plus 400-watt inverter provides portable power for trucks, RVs, boats, and minivans. By plugging the inverter directly into your vehicle's 12-volt cigarette lighter, you can turn your vehicle into a mobile office and operate devices such as a 27-inch TV or 20-inch TV/DVD combo, a camcorder, and a laptop computer. This compact, lightweight unit automatically senses low battery voltage so you never have to worry about a depleted battery. It's a quiet alternative to noisy, gas-powered generators; it will provide hours of emergency power during snowstorms or blackouts. The high-efficiency design transfers 90-percent of the battery's power to your equipment, providing 400 watts for 5 minutes, 600 watts surge for easy startups, and 300 watts continuous power for operating appliances. An automatic shutdown mechanism protects against overload, over-temperature and low battery conditions. The inverter is equipped with two 3-prong grounded AC outlets, a DC outlet and hardwire applications. The durable plastic unit is 5.9-by-4.1-by-2.2 inches in size and just 2.4 pounds in weight. It is covered by a 1-year warranty.
