Automatic AC voltage regulator circuit

The RTD temperature sensor, as illustrated in the subsequent figure, collects temperature data from the field. This data is converted into a voltage signal by the XTR105, which is then transformed into a 4 to 20 mA current output....

The rewiring of an entire house is underway following a significant malfunction of two antique knob and tube circuits. A challenge has arisen with the outdoor lighting setup, specifically concerning a detached garage that features a porch light above...

The circuit receives its input from the zero-crossing detector, which generates a 0-to-1-to-0 pulse to set the R-S flip-flop and activate the ramp circuit (A to Ramp) to initiate the timing ramp ascent. The described circuit operates by utilizing a...

PLC input cards typically do not provide power, necessitating an external power supply for inputs and sensors. An example of an input card and a ladder logic diagram illustrates how to connect an AC input card. The PLC inputs...

Useful for narrowband frequency modulation (NBFM) reception on older shortwave receivers that lack this capability, this circuit employs a phase-locked loop (PLL) integrated circuit, specifically the N565N. It was originally designed for use with an old Hammarlund HQ-170 receiver,...

The car power amplifier utilizes the SI1050GL integrated circuit (IC) as the primary amplification component. It delivers an output power of 50 Watts at an 8-ohm mono impedance. The amplifier operates with a DC voltage of up to 25...
