Digimax pure wave DC/AC converters: advantages and applications

An electronic DC/AC pure wave inverter is a device that converts DC input current/voltage to AC output current/voltage, with the possibility of varying its value and frequency. The current produced by the inverter has an ideal sine wave shape, i.e., pure wave, which is the same as the alternating current in the domestic electricity grid.

Pure wave DC/AC inverters are often used to power sensitive or high-precision equipment for which power quality is essential, as these DC/AC inverters provide stable, high-quality voltage: computers, televisions, control and emergency power systems, photovoltaic systems, electric cars, and charging devices.

The Mean Well pure wave DC/AC converters distributed by Digimax are known for their reliability and durability.  They are available in different power ratings and configurations and are mainly used in renewable energy conversion systems (solar, wind, etc.) and uninterruptible power supplies. They also have multiple overheating, overload, and short-circuit protection functions.

Pure wave inverters: when to choose over modified wave

In accordance with the output waveform, two types of inverter can be identified: pure wave and modified wave. Pure wave inverters provide a qualitatively better sine wave signal at the output than modified wave inverters, and may therefore be preferable to modified wave inverters for a number of reasons:

• The pure wave provided by DC AC converters reduces the risk of electromagnetic interference, which can cause problems for sensitive electronic systems and data transmission;
• The pure sine wave transformer allows maximum power to be obtained for a longer time, since unlike the modified wave, no voltage drop occurs: the powered device will therefore operate more efficiently and reliably.
• The pure sine wave produced by the DC/AC inverter is less susceptible to noise and electromagnetic interference than an irregular waveform, such as that of a modified wave DC AC converter, improving the stability of the power supply.
