Relays are very important electrical devices, and choosing the proper one is very crucial. Relays usually incorporate an electromagnet, which is activated by a current or signal in one circuit to open or close another circuit. There are numerous factors that should be taken into consideration when choosing the proper relay for a job, including the contact system, magnetic system, the environment, and the physical requirements for installation.

An Introduction to Voltage Regulators

Voltage Regulators

Voltage Regulators

A voltage regulator is found in electronic devices, and it is used to maintain the voltage of the power source so that it stays within acceptable limits. Voltage regulators are designed several different ways – it could be a simple “feed-forward” design, it may include negative feedback control loops, or it could use an electromechanical mechanism, or electronic components. Also, voltage regulators may be used to regulate one or more AC or DC voltages, depending on the design.
