Sterling Pro Power Quasi Inverter 12v 100W Socket Type: Universal Voltage DC: 12 Power (continuous) Watts: 100 Size L x W x D mm: 65 dia 145 Weight Kg: 0.2 General opinion over the last few years was that the quasi-sine wave inverter was dead and the pure sine-wave inverter would rule the world (an opinion not shared by Sterling). Sales of quasi-sine wave inverters have continued to out-grow sales of pure sine-wave, proving that there is plenty of life left in this technology. The principle reason is that most of the equipment such as mobile phones, TVs, drill chargers and all that type of equipment which used to have a problem working with quasi-sine wave tends to now work fine on quasi-sine as the effected equipment tends to use a switch mode power supplies in the design which works fine with quasi sine wave. This meant that rather than the problems getting worse over the years the problems have diminished, however, this is not to say that the odd microwave, drill, vacuum cleaner would not work (if there is a thyristor control circuit employed then this can still be an issue) but there is no question this is becoming more rare as the years go past, plus, it usually is a lot cheaper to replace a £35 microwave to a different model which will work rather than spend £700 on a sine wave model to make it work .
Sterling has invested in a new range of quasi-sine inverters because they are smaller, lower cost, offer better performance, are more efficient and more reliable than sine-wave. We, at Sterling, have always found the quasi-sine wave inverter more than adequate for general requirements in boats and vehicles. There is still the odd appliance, such as washing machines, where quasi-sine wave inverters simply do not work but all in all they do a great job - especially considering their cost. With this in mind, we have made a new range of DIGITAL quasi-sine inverters called the Pro Power Q. The idea behind this was to push forward this technology and bring in some new features. The most obvious change in this new inverter is its style, tough aluminum extrusion with great looking plastic end caps. Euro and British sockets are on all this range, enabling the unit to be compatible across Europe without problem. The new extrusion design has allowed us to reduce the size of the 1000-2500W units by nearly 40% but still offer their full power and even better performance over the previous models. If you also require a battery charger then look at our new Pro Combi Q range. Noisy fans was always a favorite complaint with our standard range, So for power to size ration this new larger size Pro Power Q range is simply unchallenged.
