DC/AC Inverters – also referred to as power inverters or rotary converters – convert direct current (DC) into alternating current (AC). Two standard types of inverters are distinguished by the waveform of their output voltage: Modified Sine Wave Inverters (trapezoidal voltage) and Pure Sine Wave Inverters (sinusoidal alternating voltage).

Due to their higher technical complexity, Pure Sine Wave DC/AC inverters are noticeably more expensive. However, because they better replicate sinusoidal grid power, significantly more types of devices can be operated with them. In contrast, rotary converters with trapezoidal voltage output cause complications for many consumers (e.g., motors, transformers, LED lights), such as interference, increased noise levels, or reduced efficiency. Certain devices, such as incandescent bulbs or heating appliances, can still handle the rectangular voltage curve without issues. For such consumers, modified sine wave inverters are quite attractive due to their low price.

At ProConnecting, both Pure Sine Wave DC/AC Inverters and Modified Sine Wave DC/AC Inverters from MEAN WELL are available. Depending on the model, DC voltages such as 12V, 24V, and 48V are applied via a cigarette lighter plug or battery terminals and converted into 50Hz/60Hz 230V alternating current (AC) . The connection of the consumers is made via a standard Schuko socket (CEE 7/3).

MEAN WELL Modified Sine Wave Inverters are available at ProConnecting in rated power outputs such as 150W and 300W , while MEAN WELL Pure Sine Wave Inverters are available in rated power outputs such as 200W, 400W, 700W, 1,000W, 1,500W, and 3,000W .
