Summary:
Circuit function and advantage
The high-side current monitor may experience an overvoltage condition after a transient or when connecting, disconnecting, or shutting down the supervisory circuit. The circuit shown in Figure 1 uses an ADA4096-2 op amp with overvoltage protection as a differential amplifier to monitor the high-side current. The ADA4096-2 features input overvoltage protection for inverting or latching for voltages above 32 V and below the supply rail.

AC Contactors
Magnetic AC Contactor is divided into AC contactors (voltage AC) and DC contactors (voltage DC),which are used in power,distribution and power applications.In electrical engineering, because it can quickly cut off the AC and DC main circuits and devices that can be frequently switched on with high current control (up to 800A),Magnetic AC Contactor is often used as a control object for motors, as well as for controlling plant equipment. The electric load of the electric heater, the working machine and various power units, the AC Contactor/DC Contactor can not only turn on and off the circuit, but also has a low voltage release protection. The AC/DC Contactor has a large control capacity and is suitable for frequent operation and remote control. It is one of the important components in the automatic control system.
AC Contactor is our mainly products,we have our own research and development team,we are always commited to provide the good quality,best service to all of our clients.Our AC Contactor had experienced many changes,so you can see that Economic AC Contactor-New AC Contactor-Super AC Contactor,also have LC1-F AC Contactor etc,in order meet different kinds of customer's requirements.
