Average Reviews:
(More customer reviews)This book is extremely basic with many errors.
Many figures/electrical drawings are incorrect and poorly done. Two examples follow:
Fig. 44-3: The description of operation of the solid state relay is incorrect. The PTCR is not in series with the start winding but is used to trigger the TRIAC which is in series with the start winding. This is a very interesting circuit and deserves proper explanation.
Fig. 55-1: Is supposed to depict an auto transformer motor voltage control. Instead it depicts what a control would look like using inductors. An auto transformer for voltage control would resemble a "buck" connection.
There are many, many more.
This book obviously was not proof read before publication.
