The circuit was designed to build a stable power supply the will provide a regulated voltage from 40 V to 70 V in a 3 A current. 2N3055 – a complementary Silicon Epitaxial-Base planar NPN transistor ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

Controlled by way of a 0V to 5V DAC-compatible programming voltage, these miniature high voltage power supplies are designed to deliver from 0V up to 8,000V, positive or negative, depending on model.

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...
