Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI

Power filters are electronic circuits designed to locate and eliminate surges, harmonic transient currents, spikes, and other unwanted signals in power distribution systems and electrical equipment such as computers, television sets, and other devices

Voltage and current signal conditioners amplify or modulate AC or DC current or voltage and process signals to improve transmission

Enclosure air conditioners remove the heat generated by electronic devices from the inside of cabinets or enclosures.

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices.

Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection

Electrical connectors are devices that join electrical circuits together.
