Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

A specialized test gadget that tests continuity quantitatively in both AC and DC modes could prove to be an indispensible bench test instrument. This article describes such a continuity test set up, ...

AC testing of electronic systems often requires a low-distortion signal source to excite a DUT (device under test). Instead of using a signal generator and a power amplifier to produce a ...

The growing demand for efficient battery testers. How to calculate ac power requirements. Calculating ac power per phase for a three-phase system. One major factor driving the lithium-ion battery ...
