Offering superior quality true sine wave output, the Prosine 1000 and 1800 stand-alone inverters are ideally suited for electrical systems that already have a quality multistage battery charger. Designed for recreational and industrial applications, their 120-volt, 60 Hz AC power output is capable of handling both heavy duty and smaller, multiple AC loads. Prosine inverters include a backlit LCD display panel, which can be mounted remotely.
A 3000 watt pure sine power inverter produces cleaner power than a modified sine power inverter, and our line of pure sine models will cover all the complex electronics that are part of our everyday lives. A pure sine wave will replicate the kind of the power you get from utility grid, providing a wide range of benefits. This kind of clean power will allow electronics to run more efficiently than they might on modified sine wave DC to AC inverters.
For today's sensitive electronics, it makes a huge difference. Pure Sine Waves (PSW) allows these electronics to run cooler (less cycling), cleaner, and with less noise. PSW is the output form that comes from the AC Wall outlet in your house and is the most clean. Additionally, some electronics and appliances simply will not operate on a Modified Sine Wave. Sample items that will not operate on an MSW are: some laptops, printers, coffee makers, dimmers, digital clocks, fluorescent lights, fans, microwaves, drills… the list goes on. MSWs can also over-heat some devices and potentially lead to the device's shortened lifespan. If you want clean, smooth, and the most pure sine wave attainable while keeping the noise down.
220v inverters, with power ratings from 700W to 30kW, feature rugged designs and high reliability while providing clean, utility grade power. Schaefer offers the industry's most complete range of input and output voltages, with a selection of package styles and mounting configurations. Some of our highly advanced designs feature integrated a UPS, static switch, battery charging and/or parallel capabilities.
Finding a device to convert DC power to AC may seem like it should be a simple task, but when you start shopping for a power inverter for your RV or road trip vehicle, you'll soon find that many choices will confront you. With prices ranging from less than $40 to well into the thousands, it can be difficult to know what features are important and how to choose a unit appropriate to your needs. While wattage, features, and connections are obvious considerations, your final choice should take into account the inverter's wave form output.
It is also important to understand that there is no way to upgrade or clean a modified-sine wave signal. If your item does not work on a modified-sine wave inverter, you will need to purchase a new true-sine wave power inverter. We often recommend that users on a tight budget purchase only enough true-sine wave power to run required equipment and purchase a less expensive modified-sine wave inverter to run the rest of the load.
