Figure 1 shows the propulsion system of an electric vehicle. It includes an electric motor, drive electronics, a mechanical transmission, vehicle control/power management, a charging system, and a ...

“You could’ve done that with a 555 timer.” But what if all you have on hand is an ESP8266? [TechColab] needed to control a solenoid valve with a short pulse via a solid-state relay (SSR) but found ...

When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

Short ac powerline dropouts can cause incomplete power-on resets, leaving the microcontroller and logic circuits in an indeterminate state. This susceptibility can be tested using a very low-cost ...

Solid State Relays (SSR) are contactless switches widely used to control large current loads with a small input control signal. ATO's SSR product line includes single-phase and three-phase relays with ...
