The control circuit can operate at the same voltage as the power circuit as well as at lower voltages by using a machine tool transformer to step down the voltage to lower levels. The electric utility ...

The primary of the transformer connects to the power line inside the enclosure but after the disconnecting means. The secondary feeds the control circuit. The preferred secondary voltage today is 120V ...

The transformers can be used in control circuits and HVAC equipment applications. Foster Transformer, 3820 Colerain Ave., Cincinnati, OH 45223; 800-963-9799; [email protected]; ...

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...

This SCR phase control works much like the common TRIAC dimmer, but has numerous advantages including increased current capability, robustness and absence of minimum voltage “snap-on.” A complementary ...

Synchronized closing applications include shunt capacitor banks, shunt reactors, transformers and transmission lines ... the SCS is installed as a modular component in the control cabinet of the ...
