The circuit was designed for providing a microphone line with a balance input signal to improve the quality of sound with sufficient gain and filter. NE5532 – an internally compensated low noise dual ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

Do you have problems with your existing variable-frequency drives (VFDs)? If so, 3-phase line reactors may be a very viable solution. A line reactor acts not only as a current-limiting device, but it ...
