EMC Filters

What is are EMC Filters?

An EMC or EMI filter is an electronic device used to reduce electromagnetic interference (EMI) in a power supply. It is typically used in power supplies, such as those found in computers, TVs and other electronic devices. The filter works by blocking the high-frequency noise generated by the power supply, allowing the device to operate more efficiently and with less interference.

DC Filters
Single-Phase Filters

E-T-A Electronic Overcurrent Protection

Image

E-T-A Electronic Overcurrent Protection Devices are ideally suited to protect equipment components in industrial applications and supply lines which are fed by means of a DC24V switch-mode power supply.

Electronic overcurrent protection prevents dips of the output voltage of switched mode power supplies both in the event of short circuit and overload. At the same time these devices provide selective protection or disconnection. Switching high capacitive loads and indicating a functional error is possible without any problems. Fault indication is by means of LEDs and auxiliary contacts. This helps with trouble-shooting and increases machine run times.
