Product Description And Application

WBI412N95 makes use of a special isolation module to monitor the AC current in the grid and circuit in real time and transform it into the standard DC voltage output; it has various kinds of advantages of high precision, high isolation, wide frequency response, low drift, low power consumption, wide temperature range, strong anti-interference ability, wide operating power range and so on. This product adopts card-mounted structure, terminal wiring, easy installation, input, output, power supply three isolation, suitable for power equipment, power network monitoring automation system, industrial control monitoring system, railway signal system.

This product meets the requirements of IEC standards. It’s well known that the IEC 61000-4-2 standard covers the system level of ESD immunity. Electrostatic discharge can be very harmful to a system and even a small amount of voltage can damage the electrical components. Most systems require some sort of IEC ESD protection, as any user accessible areas will be subjected to ESD strikes.
