The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...

This circuit is a very simple voltage monitoring device for +5V VCC supply lines. It can be used to monitor the power supply of a microcontroller (uC) by indicating when the supply level raises above ...

He chose the voltage-setting resistors R1 and R2 to give him 2.5 V on the TL431 when the output sees 3.6 V, the voltage which a LiFePO4 battery is basically done charging.

Promising to simplify high-side current sensing in a wide range of high-voltage circuit protection applications, the ZXCT1080 current monitor provides an extended, common-mode-sensing voltage ...

He says that the voltage monitor works quite well, and we’re sure he feels a lot better about the health of his car’s charging system.

Circuit monitor maximizes facility uptime The CM4000T PowerLogic series circuit monitor features transient detection to detect and record transient voltages that exceed the voltage-withstand of ...

Often, a circuit operating at 5 V must monitor currents at 48 V. Techniques using costly high-voltage difference amplifiers and other special devices can measure such currents, but the circuit in ...

Power feed modules can accommodate cables up to 16 mm 2, and the electronic load monitoring modules can accommodate cables up to 2.5 mm 2. With maxGUARD from Weidmüller, panel builders can now easily ...

ABB introduced a new remote monitoring solution for any OEM circuit breakers filled with sulfur hexafluoride (SF6) gases, at its booth at the IEEE PES T&D Expo. The Circuit Breaker Sentinel, or CBS-F6 ...
