Jecod Sine Wave Wavemaker PumpsJecod Sine Wave Wavemaker Pumps. Conventional AC power is produced by rotating machines (alternators) that produce a smooth alternation, like that of a pendulum. It is described mathematically as a sine wave. It is the ideal waveform for the transfer of AC power. When converting AC to DC power most DC controllers will convert the AC power to a DC Square wave or DC modified square wave. For the most part a DC Modified square wave will often emulate a
